Stamparono i francobolli singolarmente a mano?

Questo - a quanto ho capito - non si sa con certezza: si suppone che alcuni di questi accrocchi venissero affiancati per la stampa di piu' esemplari.
''According to the standard work, The Postage Stamps and Postal History of British Guiana by W. A. Townsend and F. G. Howe, Royal Philatelic Society, London 1970, p.25, the frames were formed by pieces of printer’s brass rule, bevelled at one edge and blunt at the other edge. Each piece of the rule was 23 mm wide and 82 mm long and, after being bent, was soldered at the junction so as to make a tube. Into the tube, pieces of printer’s type were fitted to form the inscription and value.
Some, but it is not certain how many, such assemblages were gathered together for the printing. After one value had been printed, the appropriate piece of type in each tube was removed and replaced by another piece of type for the next value to be printed. For the 12 cents value, two pieces of type had to be inserted''.
