Over at the blog We Made This, there’s a scan of an article in a 1975 issue of Design Magazine that covers the construction and guidelines for the 1976 Montreal Olympics Logo designed by Georges Huel. It’s interesting to see how the logo was developed over a grid system.
The logo represents a podium, a running track, the letter M and the olympic rings. Simple and brilliant. I personally prefer this mark over the one created by Otl Aicher for the 1972 Olympics.
