Colombia– 1861, “Nueva Granada” 1p six glass support clichés, showing a startling array of colours, from red and vermilion, to a radiant blue and black (with production notes about the Alpha celluloid and the Calor lamp used for light exposure), also an neat glass cliché of the small Bolivar 10c, mirror image. Unique and a very attractive and colourful group, with less than 10 glass clichés recorded, and the Bolivar issue first time offered at auction.
