The 11th Commonwealth Games, held in Edmonton in 1978, featured cycling, weightlifting, badminton, wrestling, boxing, swimming, shooting, bowls, and track & field, including a marathon. Canada had the opportunity to choose a tenth sport for 1978 and selected gymnastics. The stamps were released as a series of six — 3 X 14¢ and 3 X 30¢. Each designed to work in colour aligned 'se-tenant' pairs each set against an elegant background of horizontal bands of silver and grey, common to all.
