Raymond-- I built a set of Topps 1981 Thirst Break Comics, which has a baseball subset. The Comics served as a wrapper around individual pieces of gum. I think the gum was originally greenish. I bought a couple of unopened boxes to finish the set. Cleaning the gum off the comics was not easy. The gum is now brownish, but very gooey and juicy. I have several pieces left. Would be happy to send you some if you promise to have someone take an I Pone video of you popping it in and starting to chew and then posting it here
Maybe we can scrounge you up a 1963 Fleer cookie as well
