Festival Titling was designed by Phillip Boydell and cut by Monotype in 1950 as the official display face for the Festival of Britain, a national exhibition held throughout the United Kingdom in the summer of 1951. The typeface was used for all official Festival announcements and was made available for general use in 1952.
A shadowed fat face (or lettering?) usually accompanied the Festival logo, representing the year. I don’t know it, but Ingeborg Block, an unrelated contemporary typeface, is similar.
The Festival of Britain was organised by the government to give Britons a feeling of recovery in the aftermath of war and to promote the British contribution to science, technology, industrial design, architecture and the arts.
