Lot 80019 – British East Africa – 1890-94 4a, four glass support clichés

British East Africa – 1890-94 4a, four glass support clichés with reversed image impression and in a range of shades, warm brown (dated Feb 1921), vermilion, gray-black and pinkish-red (defective), also three (presumably) genuine unused stamps in values 8a and 1r that Sperati would have used as the basis for developing his reproductions; an exceptionally scarce range of colourful clichés, with only very few glass clichés recorded and no examples found in the B.P.A. collection.
