I think anyone with half a brain could figure out that pin up artists took plenty of artistic liberties with the rendering of their models. However, it is still interesting to see photos of the original models taken in the artist’s studio put beside the resulting picture. To me, many of these pictures are actually fairly faithful to their original photographs. A lot of the “retouching” in these is simply giving the model a different face. To me it seems like this was done more for variety in the faces than fixing “imperfections” that artists saw in the models.
