Here's another great find courtesy of our friend Amit Benyovits. This set of 30 small cards comes out of Barcelona, Spain sometime around the 1931 release of the Chaplin classic City Lights. Issued by Eduardo Pi, a chocolates and cocoa company, the backs clearly note the size of the set with the text Las luces de la Ciudad at the top of each card, translation: City Lights.
Amit notes that the cards are printed on a thin stock paper with glossy fronts and gummed backs. He has also submitted two different variations of the backs, one with brown lettering the other with black. An example of each reverse side appears just below this text and above the gallery of all 30 Eduardo Pi City Lights cards:
