Centennial Baby Sisters Circa 1967 Experimental Essay, block of 18 showing two young girls. Tête-bêche between the two blocks of 9 and imperforate vertically between one column and a vertical straight edge. Engraved printed in colours ranging from green to black with never hinged Davac gum. Shows an interesting variety of a vertical unprinted area. In 1967, British American Bank Note Company was awarded the contract to print the Centennial issue booklets using a new printing machine, a Goebel press, which could print booklets of multi-coloured stamps in one operation. They tested the new press by printing booklets using a design referred to as the "Baby Sisters". Very fine. (Image)

A most unusual illegal use for these which passed through the postal system in the proper period where the 6c coils would have been used. A must have for any Centennial collector, very fine. (Image)
