The red telephone box evolved into an iconic symbol of the United Kingdom since Sir Giles Gilbert won a 1924 design competition. That earliest cast iron model was called Kiosk No. 2 or K2. The Tudor Crown feature was added in 1926. Five additional models were introduced before production of the public phone booth stopped in the mid-1980’s. Only about 11,000 of the total 314,000 telephone boxes remain in service. This row of K6s bearing the St Edward’s Crown are on Broad Street. Their primary purpose today is as a photo opportunity using – what else? – a mobile phone.
