These gorgeous curvy pin-ups are the works of George Petty. He was one of the top "cheesecake" illustrators of the 30s and 40s.

Petty began his career with a series of cartoons featuring beautiful girls and their not-so-handsome beaus. His work sparked the term "Petty Girls", describing the carefully airbrushed girls with brilliant smiles and sexy poses,

He left Esquire and was replaced by Alberto Vargas, to become a freelance commercial artist. His girls soon ended up gracing magazine ads and calendars. Though extremely sexy and kinky, you have to admit his work is really impressive.
