Who'd be a ref? Cartoons set to go under hammer at Bonhams auction house in London

Referees have never been held in highest esteem - a perception unlikely to be altered when these two cartoons go under the hammer next Wednesday (December 13, 2023) at an auction to be conducted by Bonhams of London. The pre-sale guide price for the one, above, by Ronald Searle (1920-2011), is £600-800, while that for the one, below, by Norman Thelwell (1923-2004) is £400-600.
