Solomon Pond Mall, Marlborough MA, April 4

Whether you are an old hand, or new to collecting, the great Cardboard Promotions show at Solomon Pond Mall is a must see. This show continues to impress, with a diverse mix of vendors selling Pokémon, One Piece, sports cards vintage and modern, memorabilia and more. Throw in some fantastic autograph guests and you have a fantastic recipe for a great day. Think of it as an Easter Egg hunt for grown-ups!

The show is at Solomon Pond Mall in Marborough, and it runs from 10 a.m. to 6 p.m. The Pennysleever recommends getting there early, since the best selection is available at the start. Naturally, we'll have our full line-up of supplies, including toploaders, card sleeves, magnetics and more. Find us in the center of the show, near the Cinnabun. Can't wait to see you there!
