Unequivocally the most famous and valuable paintings in Brock's career were his golf paintings – "The Bunker"; "The Drive;" and "The Putt" – all of which were painted in 1894 as part of the same series. These paintings were acquired together by a Japanese collector in 1991 for $1.5 million. The most valuable of these is "The Putt", which was repainted due to the position of the caddy and bystander as the commissioner of the painting wanted to bring himself, the putter, more into the forefront of the painting. The initial unsigned painting is considered to be the more impressive of the two versions, and is even used as the print for postcards and posters sold in many golf museums.
