Décalcomanie

Once you saw these in every French hatters shop window: décalcomanies for berets.

Decalcomania, from the French décalcomanie, is a decorative technique by which engravings and prints may be transferred to pottery or other materials. Today the shortened version is "Decal".

The time of all men wearing berets is long behind us, and so is the diminishment of these little arty window pieces.

And like everything that's become obsolete, rare and vintage, they actually fetch high prices on auction web sites and at antique markets.
