Sc. 5252-3/3040-1 History of Hockey on a 5"x7" Dragon Card featuring a close-up photo of a hockey skate, stick and puck. The U.S. pair of stamps and pictorial cancel are on the left. The Canadian pair of stamps and cancel are on the right. Note that each country's postmark was applied in that country and is the official size for that country. Great for a hockey- or sports-on-stamps collection!
