This vintage real photo features a pretty young woman partially disrobed. She is wearing hoop earrings and a very long necklace. This postcard is risque for its era. Tasteful nude postcards were considered art during the time that this postcard was issued. The card was published by the French firm, P.C Paris as part of a series (No.2484). The P.C logo is an abbreviation for Papeteries d Levallois-Clichy. The firm published a variety of real photo postcard topics including portraits of pretty models, nudes, views, and holiday cards. The company was active in the 1920’s. (SOLD)
