After reading Marc’s recent post in this forum about Fleer GOOFY GAGS, it reminded me of 2 other non-sports releases that are also sometimes overlooked by collectors because they were issued as bonus inserts in packs of Topps football cards. These non-sports releases are FUNNY RINGS (issued in 1966 Topps football packs) and KRAZY PENNANTS (issued in 1967 Topps football packs). A complete set of FUNNY RINGS is 24 cards (plus checklist) and a complete set of KRAZY PENNANTS is 31 stickers.
Posted here are pictures to show examples of the wrappers for these 2 releases. Through various sources, I was able to identify at least 3 different ad wrapper variations for each of these releases. They are as follows: FUNNY RINGS (wrapper ads for Indian Headdress Kit, Magic Magnet Set, and Camera) and KRAZY PENNANTS (wrapper ads for Exploding Battleship, Chemical Magic Set, and Camera).
Copied below are links to websites that show example pictures of some of the cards/stickers from these non-sports sets along with additional information. These non-sports issues are also listed and described in the Sport Americana Price Guide to Non-Sports Cards covering non-sports releases from the 60s and 70s.
