2025-26 Topps Signature Class Basketball Jumbo Box

Cooper Flagg's NBA rookie auto — and it's right here. The 2025-26 Topps Signature Class Basketball Jumbo Box is the NBA debut of Topps's autograph-first brand, and the Jumbo configuration is the most loaded way to crack it open.

Configuration: 4 packs per box · 10 cards per pack · 4 autographs per box · 8 boxes per case.

The foundation is a 150-card base set with 50 rookies, each printed in both Paper and Chrome versions. The Paper parallel rainbow runs Coral /299, Green /150, Red Lava /25, Black /10, Blue /5, and the one-of-one FoilFractor. Chrome adds the Refractor, Pandora (unnumbered), Gold /10, and the iconic Superfractor 1/1.

Autograph subsets span Chrome Autographs, Crystal Clear Autographs on acetate stock, Shadow Scripts, Manuscripts, Signature Blend, and the artistically tree-inspired Eternal Marks. Key signers confirmed across the checklist include Cooper Flagg, Dylan Harper, Ace Bailey, Kon Knueppel, LeBron James, Victor Wembanyama, Shai Gilgeous-Alexander, Stephen Curry, Kevin Durant, Magic Johnson, Larry Bird, Shaquille O'Neal, and Hakeem Olajuwon. Dual Autographs pair legends and phenoms — think Cooper Flagg/Dylan Harper, Carmelo Anthony/Jalen Brunson, Paul Pierce/Kevin Garnett, and Hakeem Olajuwon/Kevin Durant. There's even an OKC Triple Auto: SGA, Jalen Williams, and Chet Holmgren on one card.

Hobby-exclusive short prints include the butterfly-themed Monarchs of the Game and the massive Leviathans SPs. Inserts across the product include High Fidelity, Pure, Unfazed, Roses, and After Image.
