Lot 70521 – 1957-72 Dollis Hill trials, 2d red-brown, wmk multi Crowns to the right, with green all-over phosphor in strip of seven

1957-72 Dollis Hill trials, 2d red-brown, wmk multi Crowns to the right, with green all-over phosphor in strip of seven with only the top halves of the stamps printed and cancelled by Middlesex 29 FE 1972 cds. This was caused when the fragile handmade paper used for part of the trials had torn and was repaired during the printing process with tape which was then printed on. This tape has become detached leaving only the top halves of the stamps printed. The strip shows machine cuts to the top, bottom and left hand margins giving the impression of having been dispensed through an automatic affixing machine.
