Great Britain 1887 Queen Victoria Jubilee Issue One Shilling Postage Stamp

This is a Great Britain postage stamp from the late Victorian era, specifically the 1887 Jubilee Issue. The stamp is printed in a dull green ink on paper and features the profile of Queen Victoria within a central oval frame. The design includes the text 'POSTAGE & REVENUE' at the bottom and 'ONE SHILLING' at the top, both enclosed within a hexagonal frame border. Small check letters 'C' and 'D' are visible in the corners, which were used to identify the stamp's position on the original printing sheet. The stamp is in a used state, indicated by a heavy black circular date stamp or barred killer cancellation that obscures much of the central portrait. The physical condition shows signs of age and wear; the perforations are intact but appear somewhat uneven and possibly toned or soiled with grime. There is visible staining or 'foxing' along the bottom edge, and the overall paper has yellowed with a distinct patina. This specific issue represents a significant period in British philately, marking the 50th anniversary of the Queen's reign with a transition to dual-purpose postage and revenue usage. The craftsmanship reflects the intricate line engraving typical of De La Rue & Co. printings of the late 19th century.
