Sometimes overlooked because it's a non-sports issue that came in a sports wax pack (1963 Fleer Football Cards) is the 54-card set known as Goofy Gags. There are a few on ebay now, and a lot of 24 or so recently sold on ebay. I have been looking for one particular one for a long time and I have many to trade!
The wrapper, display box, and an unopened pack can be seen here. You can see on the front of the wrapper it says: "Extra! Free Goofy Gag Card" (and there is a similar phrase on the front of the display box):

A very interesting idea! I'll admit that I wouldn't have thought of this one but it DOES make sense! Definitely a nonsport card in a wax pack with gum which qualifies in my opinion. Welcome Marc and thanks for posting! For anybody just joining us, Marc wrote the Big Wad articles in the last two Wrapper magazines (see link page if interested). Any other opinions?
Those goofy gags cards look like they bring pretty strong prices. Which card are you looking for? I will keep an eye out.
Thank you Dude! The card I am looking for is: "I Welcome Criticism - Write Yours Here."
Fleer Football with Goofy Gag Cards is added to checklist version 1.06!
Thanks Marc!
