Some things you just have to see to believe. Until this piece, we had never seen Tiger write "Tiger Slam" before. I guess it counts as signing twice, as his first name is present in this rare signature/notation. Tiger signed this large piece for his exclusive autograph partner Upper Deck Authenticated. It was almost certainly destined for only Upper Deck's best accounts, as only 50 were produced, of which this is #39. 16x20" Giclee framed to 21x25".
