This is a small, two-side promotional coupon flier for Superman French Fries, a grocery product sold in the early 1983s by Canada Fancy in Canada only. This specific flier measures about 5-3/8″ wide x 8-1/8″ high and includes a 29 cent coupon. The back of the flier has a promotion for a special Superman french fries kite offer available on specially marked bags.
Of interest to Super Powers collectors: The Super Powers Hall of Justice uncovered an amazing Superman French Fries bag with a Super Powers action figure instant win contest that also included a Clark Kent mailaway. I can’t imagine many of these have survived.
