CBC Annual Report 74-75 graphic. The forms are incredible but the blue is a bit too royal-blue for my tastes. With a more muted color scheme and a shift of the blues into the aqua realm this would be on a whole other level. But I am assuming if you found a copy of this today, it would have faded just enough to look pretty amazing.
