Cayman Islands: 1935 Pictorial 11/2d. black and orange, a fine mint example showing the rare offset variety. "A copy exists of the 11/2d. ... with a ghost-like impression of the King's Head on the back. It is obviously an off-set impression of the central vignette. It is not known whether it is constant." ("The Cayman Islands, Their Postal History, Postage Stamps and Postmarks" by E.F. Aguilar & P.T. Saunders, 1962). S.G. 99 var. Photo. (Image1)
