Alberto Vargas Paintings have mostly to do with...ahem, you look and you understand by yourself.
Other links with more pictures of his work:
I didn't know about Vargas until I started airbrushing. Vargas used to airbrush some portions of his drawings to save time. But he actually would draw them by hand.
In any case, I din't know that he was known for his pin-ups mostly. And this topic allows me to say one word about sensuality in art. I think that in modern paintings or drawings and illustrations and drawings (and I would include these, too), and in our current society full of sexual hints and even direct allusions, we have totally lost the term "sensuality". By showing too much we have impoverished our capacity to imagine.
