From the Gibson Girl to Betty Grable, "pin-ups" have been popular American art. The drawings of Vargas and the Sports Illustrated Swimwear issue are both "cheesecake". From the very beginning Las Vegas saw the value of including pretty girls in their publicity and cheesecake photos were sent out on the wire everyday to newspapers around the world. Scantily clad, leggy or busty beauties in bathing suits by hotel pools, lounging on golf courses, in showgirl costumes around town were the staple of Las Vegas glamour photos with some starlets, cocktail waitresses and cowgirls thrown in. Of course, any holiday was a reason to put a girl in a sexy costume for a publicity shot. Even the change to daylight savings time created a reason to paint a clock on a showgirls navel and shoot a picture. Las Vegas, like no other city in the world took advantage of the media's willingness to spice up their publications with photographs of beautiful, glamourous, sexy women from Las Vegas.
