2026 Topps Museum Collection Baseball Hobby Box

Each box contains a single pack, with the contents concentrated in a few higher-quality cards.

The base set covers 100 cards with players from several generations of the league. The autograph lineup returns to the series' established structure, including Museum Framed Autographs, while Atelier Autographed Books combine images of the players' home ballparks with signatures in a card that folds open like a book. Memorabilia remains a core part of the edition through relic cards and autograph relic cards. This year's cover features Ken Griffey Jr. in a Seattle Mariners jersey.

A sealed hobby box. This is the channel where the manufacturer's autograph and parallel cards are inserted, unlike the retail formats. The hobby format is distributed only to specialist retailers and has a different card mix than retail.
