THE COLLECTION

MLB-Cleveland Guardians

Authentic Cleveland Guardians & Indians Autographed Memorabilia Finding genuine Cleveland baseball autographs shouldn’t be a guessing game. At Autographed With Proof, we specialize in high-end Cleveland memorabilia sourced directly from the players. Whether you are looking for a signed José Ramírez jersey or a vintage autographed Bob Feller baseball, our collection is curated for loyal fans and serious investors who demand absolute certainty. Why Collectors Trust Our Cleveland Signatures The sports memorabilia market is unfortunately saturated with "pre-printed" signatures and forgeries. We separate ourselves by providing exact proof for our inventory. Every item in our Cleveland collection is backed by industry-leading authentication from Beckett (BAS), JSA, or PSA/DNA. In-Person Signings: We attend Guardians games at Progressive Field, Spring Training in Goodyear, and private signings to ensure every pen stroke is legitimate. Photo & Video Proof: Most of our items feature "proof" photos of the Cleveland player actually signing the specific item you are purchasing. Beckett Authentication: We prioritize Beckett authentication, the industry gold standard, but we also offer items authenticated by PSA/DNA and JSA. Build Your Cleveland Baseball Investment Portfolio From legendary "Tribe" icons like Jim Thome and Omar Vizquel to today's stars like Josh Naylor, our inventory spans the greatest eras of Cleveland baseball history. We understand that a signed Cleveland photo or autographed equipment isn’t just a decoration—it’s a piece of team history. By combining rare items with airtight provenance, we help you build a collection that holds its value for years to come.
