While there wasn't a lot of responses, I have always enjoyed the miniature sized cards found as inserts.
Topps is often known for their 1952 set to the casual hobbyist, but it was their 1951 release that resembled a card game that helped to get them on the map.
Released in 1951 was a set of cards with players that you would shuffle into your deck. Based on the card you drew that would indicate the action taken for your team.
Topps has used this idea and even design many times since 1951 including the 2020 release by Blake Jamieson, one of the head artists for Project 2020 and Topps Project 70.
In 2015, Topps released a set of cards containing 104 players. It had a MSRP of $79.99 upon release. In addition to a complete set for the (roughly) $80 purchase, the box also contained 21 color back parallels and 1 autograph.
The 21 parallels were seeded into the set by the following breakdown:
Red Back (10 per set)
Blue Back (5 per set)
Green Back (3 per set)
Black Back (2 per set)
Gold Back (1 per set)
As you can see from the below picture I have all the color parallels from this miniature release.
Do you have any 1951 Topps Game cards, either modern cards that use the old design OR any originals?
