This Autographed Alternate Slate Speed Mini Helmet W/ Uv Mirrored Back Acrylic Display Case has been Personally Signed by Jason Kelce of the Philadelphia Eagles. This item is 100% Authentic and comes with a PSA/DNA Certification numbered Hologram. Please note that PSA/DNA no longer provides serial-numbered COA cards, and the attached PSA/DNA sticker will serve as the complete authentication for this item. We conducted an autograph signing with Jason Kelce where multiples of the same item were signed. While the photographs are representative of this item, the size, placement and strength of the signature may vary. Each item is hand signed, therefore, each autograph is unique. This item can be verified through PSA/DNA Holo.
