Interesting to note that the Sask Wheat Pool in 1967 painted a yellow and brown (pool colors) square cut maple leaf on most of their elevators. Only a few elevators remain with this 1967 graphic. Browse this gallery to see a few more. I remember as a kid traveling with my parents seeing the workers paint some of these. This logo was used by the pool for Canada's Expo 67 & Canada's 100th birthday.
