I AM TAKING THE TIMELESS ART OF THE PINUP GIRL AND ADDING A MODERN POP. MY GOAL IS TO HAVE MY ART IN EVERYONES COLLECTION. The term pinup girl was first introduced in 1941. Pin-up images could be cut out of magazines or newspapers, or they could be on a postcard. Such pictures often appear on walls, desks, or calendars. The pinup poster has been plastered on bedroom walls since the mid-20th century.
