From the reference box # 68

#68 - set of 4 stamps celebrating 50 years of the BBC (1922 - 1972).

Designed by David Gentleman and released on 13 September 1972, these stamps have great illustrations of equipment significant in the history of broadcasting; 3p - Microphones, 5p - Horn Loudspeaker, 7 1/2p - TV Camera and 9p - Oscillator and spark transmitter (Marconi/Kemp experiments 1897).

Here are the first day covers for each stamp, which are also pretty cool...
