Own a striking piece of baseball history with this autographed Frank Thomas Chicago Pinstripe Baseball Jersey. This is a custom, display-ready jersey—not manufactured by or affiliated with any professional league or team—crafted specifically for collectors who value provenance and presentation as highly as the signature itself.

Included with this piece is a JSA (James Spence Authentication) Certificate of Authenticity, plus a tamper-evident authentication sticker on the jersey, validating the Frank Thomas autograph for reliable, long-term ownership. The combination of the COA and visible authentication marker provides clear, verifiable provenance for display or gifting.

The back features the name THOMAS with the bold number 35, presented in a classic block font with crisp contrast against the white fabric and black pinstripes. The design mirrors the iconic Chicago pinstripe aesthetic while keeping the focus on the autograph and the player’s legacy—without league logos or brand markings to distract from the collectible value.

Size XL offers a comfortable, display-friendly fit that’s ideal for framing, wall-mounted displays, or a dedicated memorabilia shelf in a game room or office. This piece stands out not just for the signature, but for its clean, logo-free presentation that suits both serious collectors and fans looking for a standout showpiece.
