Image Keywords: A classic British icon, the famous K6 "Jubilee" model which used to be seen standing on the streets the length and breadth of Britain. Designed by Sir Giles Gilbert Scott to commemorate the Silver Jubilee of King George V in 1935. The K6 soon became the most famous and best loved. These were replaced with a bland modern design in the 1980s, but many remain especially in conservation areas. They are becoming highly sought after collector items, worth in excess of £2000 if well preserved.night street London telephone box bt British Telecom classic British call phone pay coin
