In 1935, as part of the celebration of the centenary of the GWR, the railway commissioned and published Railway Ribaldry, a book of cartoons by W. Heath Robinson, giving that well-known cartoonist a free hand to re-imagine the history of the line for the amusement of its customers. The result is a 96-page softback book with alternating full-page cartoons and smaller vignettes, all on pertinent subjects.[118]
