Thomas Derrick (1885-1954), a forgotten artist, drew for Punch between 1932 and 1948, though most of his hundred-plus drawings there are from the ’30s.
This pair, published on November 6 1933 in the Punch Almanack for 1934, is a very early satirical comment on television. There are captions on both. The coruscating punchline is in the second.
Derrick had nothing to do with broadcasting professionally, but the year after the British Broadcasting Company became the British Broadcasting Corporation (by Royal Charter), he published black and white illustrations for Eleanor Farjeon’s book of 26 poems, The ABC of the BBC, William Collins, 1928.
