Cardboard Promotions Solomon Pond Mall, Marlboro MA, January 3 2026

What do you get when you combine three incredible autograph guests, 125 tables full of the best baseball, basketball, football, hockey, Pokémon and TCG cards in New England, and free admission? The Cardboard Promotions Show at Solomon Pond Mall, of course!

This popular show returns on Saturday January 3, 2026, and runs from 10 a.m. to 6 p.m., and will feature a wide selection that goes from cards to publications to memorabilia. The non-sport collectors will be well represented, too, with Pokémon, MTG, and Yugioh cards sure to be on offer. It's a family friendly show, and we'll be there with all the toploaders, sleeves, magnetic card holders, binders and cases you need to showcase your newest pickups.

Be sure to tell them Mr Pennysleever sent you!
