I collect all things Abbott and Costello. I recently acquired a rare six sheets posterof coming around the mountain and posted pics of it as. Her3. My wife wants me to sell it. I know I can get $500.00 for it. Is it worth holding onto? I have to put it in storage for several months as I look for a new home. Just wanted the opinions of other poster collectors. Also, except for this one, I am an avid collector of genre themed movie lobby cards. Thanks for input.
