Pencil signature, "Andy Warhol 68,” on an off-white 7.5 x 2.75 sheet. In fine condition, with light show-through from a collector's notation on the back. Encapsulated in a PSA/DNA authentication holder. A large autograph from Warhol that dates to the year that he was nearly killed by an assassin's bullet. He had physical effects for the rest of his life, including being required to wear a surgical corset, and the shooting had a profound effect on Warhol's life and art.
