KBS-elvgren-018-LG Gil Elvgren (1914-1980)

The picture has something of this: woman, wear, girl, people, summer, enjoyment, leisure, fun, fashion, retro, dancing, recreation, dress, outdoors, young, carefree, joy, pretty.
Perhaps it’s a painting of a woman leaning on a sign with her legs crossed and holding a bottle in one hand and a can of soda in the other hand.
