Sweden – 1855, 3sk two glass support clichés, one with note “Essai 83” and the other with faint impression “pose insuff. 3°”, also two fine clichés of the 24sk, one with mirror image in an attractive vermilion and date Jan 1937, and a cliché on celluloid marked by Sperati “36 trop d 13”. A very fine and scarce group of five items that shows Sperati experimenting with exposure and colours in preparation for the finished reproduction of the world-famous 3sk yellow.
