Burton Kramer is a graphic designer living in Toronto that played an important role in bringing the International Typographic Style to Canadian design during the 60s and 70s. He’s most famous for the excellent logo that he designed for the Canadian Broadcasting Corporation in 1974, which is pictured here. You can see some more examples of the logo use as well as a video of the logo sequence seen on TV. The Center for Contemporary Canadian Art has an excellent online archive of Kramer’s work.
