This Autographed Santa 8x10 Photo with the inscription of "Clark" has been Personally Signed by Chevy Chase of National Lampoon's Christmas Vacation. This item is 100% Authentic to include a hologram by Beckett Authentication Services. This item will come with an affixed Beckett Authentication Services (BAS) authentication sticker, which includes a scannable QR code to verify authenticity. Please note that Beckett no longer provides serial-numbered COA cards, and the attached BAS sticker will serve as the complete authentication for this item. This is a BAS Witnessed Protection Program item which means a Beckett Authentication Service representative was present when this item was being signed. We conducted an autograph signing with Chevy Chase 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.
