I discovered a whole section of memorabilia for Curious George at Bill's Old Bike Barn and Museum. Curious George was one of my favorite books as a child. I still have my copy. I really related to the curious little monkey who constantly got himself into trouble. I had a curious streak too but thankfully I didn't get into toooo much trouble!
Thank you Diana and Marilyn! It may have only been popular in the U. S. Diana. The author was H. A. Rey and it was an illustrated children's book.
@hjbenson Thanks Harry!
