SS-GB

The booklet of mock 1941 Hitler-head postage stamps is trade-and-press promotional ephemera issued in advance of publication; many were recalled or destroyed after Royal Mail objected. It is a supplied-with extra, not a point of issue — a first-edition copy is still a first without it, and its presence does not make a later printing a first. A sepia promotional postcard reproducing the Whitehall image stands on the same footing. No specific book-club issue is documented in the sources consulted; standard club tells apply (no price printed at the jacket flap, lighter boards, cheaper bulking paper, blind-stamp to the rear board).
