Lot 40073 – UNIQUE CANCELLATION REMOVAL EXPERIMENT Cancella

UNIQUE CANCELLATION REMOVAL EXPERIMENT Cancellation removal experiment on 1d in deep blue, state 2 (showing nick on bottom of 10th stamp) in sheet of 12 with red « National Bank of Ireland » cancels, the washed colours of the stamps come from the attempt to remove the red cancels which has been partially achieved but not without damaging the integrity of the stamp. This item is unrecorded by Rowse in his « Rainbow Trials » book, of which he records only three sheets with a red cancel; one in black, one in deep blue and one in black used as part of the cancellation removal experiment, of which the latter is the only item not locked away in the Royal or Post Office museum collection. A marvellous and highly important exhibition or museum piece. Estimate: € 40’000 – € 60’000
