Great Britain 1902 10s ultramarine I.R. Official, SGO26.
Very fine and fresh unmounted mint example with full original gum. Corner perforation repair at lower left, nevertheless a very attractive example of this great rarity of British philately with less than six mint example known in private hands.
These stamps from King Edward VII's reign were used by revenue officials in the provinces, mail to and from Head Office passing without a stamp. The London Office used these stamps only for foreign mail.
Only the 2nd time in 20 years we have handled this extremely elusive departmental official.
The Stanley Gibbons catalogue value is £85,000
