The Know the Game series of books first appeared in the 1950s. They were originally published by Educational Productions Ltd with modern editions still available from the publisher Bloomsbury. They were usually produced in association with an official body as in the case of Underwater Swimming where it was the British Sub-Aqua Club.
The author was BSAC First Class Diver George F. Brookes with R.B. Matkin providing the artwork. My edition is from the mid-70s but the book was originally published in 1962. Here's a selection of Mr. Matkin's illustrations:
