Gibraltar. Used. Great Britain 19th century issues, 6 line-engraved and 9 surface-printed, showing Gibraltar usages, including 1d red on piece and 2d blue plates, 1855/57 4d on piece and 6d with 'G' postmarks, 1865/73 4d vermilion wing-margin pair on piece tied by 'A26', wing-margin 1872 6d pale buff similarly tied on piece, etc. A most attractive group in superb quality. Far scarcer than their GB counterparts.
