Got this recently for a few pennies for its nice blue Jesselton cancellation. This was probably part of a horizontal imperf pair. I hope the postal clerk was responsible rather than some schoolboy collector. According to my very old SG catalogue, a 1925 3c green imperf horizontal pair used was priced at £1100!. Now half the pair, price less than £1. Is that not a act punishable by death in philately?
