Ivan Mazepa Among His Good DeedsA panegyric thesis engraving dedicated to Hetman Ivan Mazepa by Ivan Myhura, archdeacon of the St Sophia monastery in Kyiv. The sheet is built in three registers. Above, on clouds, stand the Kyiv churches built and restored at the hetman's expense, with a seven-columned rotunda between them as an image of Wisdom and the seven liberal arts; below them a row of saints. In the middle register Mazepa appears in knightly armour holding the hetman's mace, surrounded by female personifications of the virtues and the sciences; one of them holds an open book bearing his name. At the foot two putti lean on military trophies — a cannon, drums, arms and banners — flanking the Kurcz coat of arms and the mottoes HUIC OMNIS and STAT GLORIA FERRO. The Latin dedication in the cartouche opens "PRINCEPS ECCLESIARVM TRIVMPHANS SANCTA SOPHIA…", styles Mazepa a knight of the Orders of St Andrew and the White Eagle, and is dated "Kijov 8br 12" — Kyiv, 12 October. Myhura signed himself "IOANNES MIGVRA, Orientalis Metropolis Kijoviensis Archi-Diaconus". The sheet is usually dated 1706, though some scholars tie it to Mazepa's visit to Kyiv on 12 October 1705. After the anathema of 1708 images of the hetman were destroyed on Peter I's orders — this engraving is one of the few made in his lifetime to survive.

Portrait of a woman wearing a ringA black-and-white studio portrait: a young woman with short dark hair rests her chin on her folded hands, wearing a light tweed jacket. On her finger is a massive ring with a dark stone — the real subject of the photograph. A crease survives across the upper left of the print. The sitter is not identified: the publication the image comes from carries no caption. By context she is a client or a model of the house of Marchak.

Butterfly ring with heart-shaped wingsA ring crowned by a butterfly with four heart-shaped wings. Each wing is a plaque of stone shading deeply from blue-violet to crimson, outlined with pink sapphires. The body is pavé-set with diamonds and the head is a red stone in a gold mount. Maison Marchak, Paris.

Advertisement for the "La Légère" cigarette caseA vertical advertisement, white on black. At the top runs the slogan "LÉGÈRE dans votre sac, LÉGÈRE dans votre poche" ("light in your bag, light in your pocket") above an image of an open flat case. Below stand "'LA LEGERE', dernière création de Marchak, joaillier, 4, Rue de la Paix, Paris" and a line offering "a cigarette box or powder compact in gold or silver, with or without precious stones — from 750 francs". Two closed cases with Art Deco engine-turning appear at the foot.

Bib necklace with carved rubiesA massive bib necklace. The foundation is several twisted ropes of yellow gold, with white diamond-set links breaking through between them. Large carved rubies in the form of leaves and fruit are clustered across these, together with round ruby beads; the biggest stones gather at the bottom where the necklace is widest. Maison Marchak, Paris, about 1955.

"Cadeau Royal" — a jewel stand for the King of MoroccoA three-tier jewel stand on a central gold shaft, photographed against red. Each tier is made up of several shell-shaped bowls of dark stone in gold mounts; the base and the finial are of pale lilac stone banded with gold hoops. The caption on the card explains that this was the gift presented by King Hassan II of Morocco during his official visit to Paris on 28 June 1963. The signature at the foot reads "Marchak — 4, Rue de la Paix — Paris".

Model of a twin-towered churchAn architectural model of a neo-Gothic church on a dark plinth: two tall spired towers, a pointed portal, a rose window above the entrance and buttresses along the sides. Individual windows, cornices and the coursing of the walls are all reproduced. Another example of the speciality that set the factory apart — exact architectural models of real buildings made as presentation pieces.

Mechanical model of a steamshipA detailed model of a paddle steamer on a rectangular base: a two-tier superstructure with rows of windows, a funnel, a paddle wheel with its housing, gangways, railings, boats and flags at the masts. Among the factory's presentation pieces the public was especially struck by the mechanical model of the steamer Derzhava, ranked alongside the silver model of the Pedagogical Museum. This photograph is the only known image of such a work.

Benches at the windows: the fine-work shopA workshop with the benches pushed right up to the windows — the way daylight was captured for close work. The craftsmen sit in two rows with their backs to the aisle, bent over their bench pins; in the foreground stands an empty place with a lamp and the wooden skirting that caught the gold dust.

The factory's large production hallA long, well-lit hall with tall windows along both walls. Some twenty masters and journeymen work at long benches — some seated, others standing at belt-driven machines in the foreground. Tools and blanks fill the shelves along the walls. The largest known image of the factory's production floor.

Plate of diamond jewels from the firm's illustrated price listA page from the illustrated price list: eight diamond pieces laid out against black. At the centre of the top row is a tiara with alternating tall and low points, and beneath it a slender bandeau. To the left are a bow brooch with two loops and a necklace with a drop pendant; to the right an insect brooch and a necklace with a long tassel. In the middle sits a large devant-de-corsage with a bow at the top, swags and three pendants, and along the bottom row two bracelets: a wide mesh band with an oval medallion and an openwork one of garlands and drops. This is one of the few surviving images of the Kyiv factory's jewellery proper: the pieces themselves went to the melting pot after 1917, and today they are judged largely from printed sheets like this one.

Advertising card "Maison Joseph Marchak"A card in an ornamental border. At the top, against an ochre ground, is a clasp or buckle with a central ring and black appliqués, entirely paved with diamonds. Below stand "MAISON JOSEPH MARCHAK, JOAILLIER, founded in Kyiv in 1878" and two addresses: "18, Rue Cambon — PARIS" and "25, Promenade des Anglais — NICE". The house went on printing that line about its Kyiv founding on French cards for decades after the factory was lost.

Working sheet with four views of a ringA drafted sheet showing four views of the same ring: profile, from above, in plan and in three-quarter perspective. The ring is black enamel with a green cabochon and gold bows at the sides. A fine axis line is ruled across the middle of the sheet — the trace of draughtsmanship rather than of painting.
