1856: 1 s. green, unused, part o.g. overprinted SPECIMEN and perfinned P.O.E. A highly interesting perfin. variety applied on a SPECIMEN overprinted early Surface Printed issue. The historic background of this perfin. is unknown and much discussed in the GBPS newsletters in 2006. The example offered here is unique as a single with only one marginal block of four (ex Maximus 1970, ex Samuel 2003) otherwise recorded. Very rare: the theories discussed vary from an early Joseph Sloper perfin. experiment to the assumption of P.O.E standing for "Post Office Experiment".rnrnProvenance: John Keegan collection (2006).Ausruf : 250 CHFZuschlag : 480 CHF
