Original unsigned pencil and watercolor costume sketch of Diana Ross in a flowing purple and red outfit, presumably for a performance on the Dean Martin Show, on an off-white 11 x 14.5 sheet. A portion of the costume labeled “Satin” in an unknown hand, and a ballpoint notation to the upper right reads, in part: “Diana Ross, Lady is a Tramp Costume.” In fine condition. RR Auction COA.
