Pin Up Girls Ashtray Set of Four from the 1950s

Authentic pin-up girl art on gold trimmed ashtrays. SET of FOUR, featuring four different lovely ladies of the the early 1950s in provocative poses. All have original labels 'SonsCo. Japan' on the bases.  Three are in like-new condition, the fourth has a sliver chip beneath the rim.  Can't be seen from the surface.  The real gold enamel trim transfer decor on all four is 100% present. We found a huge list of pin-up girls on Wikipedia. It was fun to try and identify them, but time-consuming.  Here's the link to the entire list with bios and portraits if you want to give it a shot: http://en.wikipedia.org/wiki/Pin-up_girl#1950s .  The lady with the fishnets, short black hair and balancing on a stool might be Ava Gardner http://en.wikipedia.org/wiki/Ava_Gardner.  The buxom blonde in green might be Betty Hutton http://en.wikipedia.org/wiki/Betty_Hutton.  Guaranteed to be original from the early mid-20th century.  Each measure 4" round, ½" tall.
