France, ca. 1920-1930. Single sheet (50.2 x 595.0 [!] cm). Black, silver, ultramarine blue, and gold printing on dark grey paper.

A rare, if not unique, and extremely long and decorative example of Art Deco wallpaper. The design is a simple tessellation of rhomboid paralellograms, resulting in a pleasant repetitive pattern. The blue very closely resembles Yves Klein blue, avant la lettre. Preserved in a roll. Slight fraying, with very short tears and miniscule chips at the edge, and a few somewhat longer tears (up to 2.0 cm) at the front-end, but mostly fine, with the colouring bright and strong.
