EXCEEDINGLY rare vintage signature in black felt-tip pen on a 4x6-inch light green autograph album page, acquired in-person by inveterate child autograph hound Joyce Forrest in 1983. Other examples of his signature have been offered elsewhere for between $500 and $1200. In good condition, with light creasing to the left side, not affecting the writing itself, and the notation by Forrest along the bottom faded over time. Accompanied by a small computer-printed image of the star. Great black character actor Whitman Mayo is best remembered as Redd Foxx's jittery, oddball best friend Grady Wilson on T.V.'s "Sanford and Son" (1972-1977).
