2.75 inches square, worn as a pair in white on each shoulder by both the Canadians and Jets on both home and away jerseys late in the 1975/76 season for the 1976 Montreal Olympics. The patch was white with red lettering.  

Please don't be fooled by other vendors claiming that the blue and red patches were worn, they were not.  These are original old stock patches, not reproductions.  See testimonials for customer satisfaction.
