A presentation pack normally consists of a cardboard folder with notes about the stamps, a holder for the stamps and a clear sleeve on the outside. Great Britain was one of the first countries to produce commemorative presentation packs, with the first presentation packs being issued by the General Post Office (GPO) in 1960, when they were looking for a convenient way of packaging and selling sets of stamps for the London 1960 International Stamp Exhibition, held at the Royal Festival Hall.
