I agree with all of these remarks. When I was a boy (and I am roughly contemporary with
@Pertinax), the mass media were just newspapers, radio and television (2 black & white channels). The media were very much based in London, so if a newspaper had a space to fill, a photographer could be sent to Regent's Park or a stock photo taken from the files or from a Fleet Street photo agency. The great photographer and cinematographer, Wolfgang Suschitzky, had a particular relationship with Guy and his photos were also used in many books and magazines. The only TV series about zoos was 'Zoo Time', based at London Zoo and presented by Desmond Morris, the Curator of Mammals, and so it occasionally featured Guy. Naturally London Zoo's publicity material often used photos of Guy, so his face was frequently seen on Tube stations, buses and posters. I grew up 200 miles from London, but Guy was the only gorilla I knew about until Noelle and Mukisi arrived at Chester, my local zoo, in 1960. I didn't actually see him until I visited London Zoo when I was a student.
