OX2a Victorian officially sealed pair on blue paper, unused, upper left corner block of four, light corner bend at upper left mentioned for the record. Reportedly only 25 pairs in existence, issued without gum. These seals were printed on the blue postal stationery letter card stock and were found to be too thick to fold over and seal the envelopes, eventually being replaced with normal, white wove paper. Only recorded example of this position. VF. Greene Foundation certificate accompanies. CV $13,000 (Image)
