The London Philatelic Exhibition 1890 was held 19–26 May at the Portman Rooms, Baker Street, London. It was one of the first international philatelic exhibitions anywhere and it was the exhibition at which the Duke of Edinburgh announced that Prince George of Wales, later King George V, was a stamp collector. The exhibition marked the fiftieth anniversary of the introduction of penny postage and the issue of the first stamps.
