This Autographed Acoustic Guitar Pick Guard has been Personally Signed by Cheech Marin & Tommy Chong. 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.We conducted an autograph signing with Cheech Marin & Tommy Chong 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 is only the pick guard, it does not come with the guitar.
