Gil Elvgren and "pin-up" are two words inextricably linked - Elvgren is arguably the most famous pin-up artist. His girls decorate everything from fabric to calendars, and his inspiration can be felt in many of the modern day pin-up artists.
I absolutely adore GIL ELVGREN: THE COMPLETE PIN-UP - an absolutely gorgeous coffeetable book jam packed with stunning technicolor prints of Elvgren's girls. Published by TASCHEN (one of my favorite book companys), there is also an extensive biography (presented in three different languages!), in-depth descriptions, and was a steal at only $10!
Who is your favorite pin-up artist? If I had to choose, mine would be Alberto Vargas ^^
