1968 F.A. Amateur Cup, Leytonstone v Sutton United, at Crystal Palace 's Selhurst Park 16 March 1968, on a Spanish 1972-issued calendar card for 1973. How it found its way to Spain, to get on a nationally distributed calendar card, is anyone's guess. These cards were issued to local firms. They would have their own publicity added to the back, so different backs are known - 2 of these cards have been seen, with different designs on the backs. This is a semi-mythical card! It's infamous among collectors due to the months of sheer work in identification, graft put in by Ian Evans, Al Worth and the many members of the Football Nostalgia Facebook group, on FB Thanks to them! Priced due to its status and the immense rarity of such cards.
