Today would be the 69th birthday of artist Alan Kupperberg (born May 18, 1953). From National Lampoon Jan/Feb. 1991, "Evil Clown Comics"; story by Nick Bakay, art by Alan Kupperberg. In the actual magazine, this panel was run with bikinis drawn onto the women; the original uncensored artwork (seen here) was posted in a 2007 interview with Kupperberg.
