Reverse of Uncle Creepy Model Sheet

I obtained this piece from Wooley's Auction Gallery back in the late 1980's or early 1990's; it was packaged with one of Russ Cochran's EC reprint sets. When I received the original in the mail, I noticed the hand-written note on the reverse in the lower right-hand corner... the "JW" is James Warren, publisher of Creepy magazine; since my initials are also "JW" I always hear Twilight Zone music playing in my mind when I look at this piece!
