The Seller of Cupids by Joseph-Marie Vien1763. Collection  of the Musee National de Chateau de Fontainebleau, Paris - a UNESCO World Heritage Site.

Cupid is making a rude gesture (it has many names across the globe, including bras d'honneur, with meanings like “up yours”, “your mama”, and “f*#k you”) to show his displeasure at being so roughly treated.

The subject of Roman women buying love was considered indecent at the time the painting was first exhibited.
