Argentine OS for the Argentinean romantic comedy,
Mi Mujer Esta Loca (1952), with the quirky, caricature artwork done by Abel Ianiro. That style of art is what drew me to this piece.
The top border must have been folded under and not exposed to as much light, as it is
SO much lighter than the other 3 sides, which have all tanned a bit with age.
Thanks for the great information, too, Matias!
