Byrne joked that when he created the costume for Vindicator (who first appeared in X-MEN 109) he swiped the costume design from CAPTAIN CANUCK.

But I'd say Byrne at least at the time he said it (1980), was being very modest, because the Vindicator flag-costume is a great improvement on the original design.
