King George VI and Queen Victoria 1940 Centenary Stamp

This item is a postage and revenue stamp commemorating the centenary of Great Britain's first adhesive postage stamp, the Penny Black. The stamp features a dual portrait design, with Queen Victoria on the left, depicted in profile facing right, and King George VI on the right, also in profile facing left. Both portraits are rendered in a lighter tone against a dark blue background, creating a strong contrast. Above the portraits, centered, is a depiction of a crown. The word 'VICTORIA' is positioned to the left of the crown, and 'GEORGE' to the right. Vertically along the left edge, 'POSTAGE' is printed, and 'REVENUE' is printed vertically along the right edge. At the bottom left, the year '1840' is displayed, and at the bottom right, '1940', indicating the centenary. The denomination '2 1/2D' (two and a half pence) is clearly visible in the bottom center, between the two commemorative years. The stamp exhibits a perforated edge, typical of postage stamps. The color appears to be a consistent dark blue, with the portraits and text in a lighter, possibly grey or silver-white, hue. The stamp appears to be in good condition, with no obvious major tears or creases, and the perforations seem intact. The overall impression is one of a well-preserved philatelic item, showcasing fine engraving or printing details for the portraits and text.
