Authentic New York Knicks Autographed Memorabilia & Proof
Finding genuine New York Knicks autographs shouldn’t be a guessing game. At Autographed With Proof, we specialize in high-end Knicks memorabilia sourced directly from the superstars. Whether you are looking for a signed Jalen Brunson jersey or a limited edition autographed Karl-Anthony Towns basketball, our collection is curated for loyal fans and serious investors who demand absolute certainty.
Why Collectors Trust Our Knicks 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 New York Knicks collection is backed by industry-leading authentication from Beckett (BAS), JSA, or PSA/DNA.
- In-Person Signings: We attend Knicks games at Madison Square Garden and private signings in NYC to ensure every pen stroke is legitimate.
- Photo & Video Proof: Most of our items feature "proof" photos of the player actually signing the specific item you are purchasing.
- The 2026 Championship Core: We carry authentic signatures from the current squad, including cornerstone stars Jalen Brunson, Karl-Anthony Towns, and Mikal Bridges.
- Beckett Authentication: We prioritize Beckett authentication, the industry gold standard, but we also offer items verified by PSA/DNA and JSA.
Build Your Knicks Investment Portfolio
From legendary 1970s championship icons like Walt Frazier and Willis Reed to modern-day powerhouses like OG Anunoby and Josh Hart, our inventory spans the greatest eras of Knicks history. We understand that a signed Knicks basketball 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.
