I saw this on blowout forums earlier today and couldn't really find any info aside from what the original poster had:
It apparently came in 3 card packs in a promo where you can get the packs when you buy a factory set from the Topps website in November 2019.
The checklist is as follows:
Mike Trout
Pete Alonso
Fernando Tatis Jr.
Vladimir Guerrero Jr.
Juan Soto
Ronald Acuna Jr.
Cavan Biggio
Justin Verlander
Keston Hiura
I couldn't find any on eBay and if I looked at the pop report right, the pack is the only thing graded from the set, no singles were graded. And I didn't see it on this site as well
Does anyone have these cards bychance? They seem extremely rare.
