Considering a major change in my social media activity ... really minimizing FB, and upping IG and X, primarily to really focus on our sports card business. Bummed, though, that @cardsoholic has our name and is totally non-existent on the platform. #sportscards

I will be in Chicago this week … but to work at Lollapalooza. I arrive Tuesday noon, will be free only until Wednesday noon. It’s in great shape, bought it at a private auction here in Phoenix, looking for $4,200. Numbered 9/15.

According to @gemrate - "Roughly 9.92 million cards were graded across the four largest grading companies during the first half of 2024, up 23% compared to the first half of 2023." The sports cards world is huge and growing. @Fanatics @Topps @SportsCardInv

What an interesting tidbit: Pascal Siakam's first NBA game was the first time he had seen an NBA game! From Cameroon, where my son, Brian, did his @PeaceCorps service. 🇨🇲
