#55 - Set of 4 UK postage stamps commemorating the ‘Centenary of the first Telephone call by Alexander Graham Bell’, issued 10 March 1976 and designed by Philip Sharland.
Each stamp depicts a different kind of person in society using the telephone - a Housewife (8 1/2p), Policeman (10p), District Nurse (11p) and an industrialist (13p).
The bright, blocks of colour and simplified graphic illustrations make these stamps really pop. I love the fact that they’ve put a mini in the background of the nurse one – such a stereotype!
My set, particularly the policeman, are covered in postmarks, the set below doesn't have any so you can really see how great the designs are.
