The first issues of KGV was the ½d and 1d values, which were in the same colours as used in the previous reign. The main design feature remained the same, however, a three quarter portrait was used for the first time and the portrait was surrounded by an ornamental frame with a value tablet at the base and a crown at the top

The UK's first commemorative stamps were issued for the British Empire Exhibition in 1924. The pair of large-format stamps featured a lion in an imposing stance; they were issued twice, in 1924 and then in 1925, the stamps of each year being inscribed with the year of issue. A second set of commemoratives in 1929 marked the 9th Congress of the Universal Postal Union (UPU), held in London that year

The first commemorative stamps to be issued relating to royal events were for King George V's Silver Jubilee in 1935
