The GEP poster by Yann is an early 1930s advertisement for Paillaret’s 'GEP' product line, which was likely a range of paints or related household products sold by Droguerie & Peintures Paillaret in Vienne, Isère, France.

The poster’s design – often a die-cut point-of-sale display (PLV) – uses playful, theatrical imagery (for example, a Pierrot-like figure holding paint cans) to attract attention in the store. Its purpose was entirely promotional: to highlight the GEP products and encourage customers to buy them, combining commercial messaging with artistic lithographic style.
