You'll Laugh Your Ass Off black light poster

  

Poster is 24" by 18 1/2". Believed to be from a 1973 commercial for National Lampoon Radio show (saw it on a National Lampoon documentary see photo of tv show).

There is no information at all on poster. Has a few spots (from a liquid) and creases. Also, areas you can see where tape and tacks were used to mount to wall.

Split in poster under You'll.
