A Hockey card is a type of trading card typically printed on some sort of card stock, featuring one or more ice hockey players or other hockey-related editorial and are typically found in countries such as Canada, the United States, Finland and Sweden where hockey is a popular sport and there are professional leagues. The obverse side normally features an image of the subject with identifying information such as name and team. The reverse can feature statistics, biographical information, or as many early cards did, advertising. There is no fixed size or shape of hockey cards, running the gamut from rectangular to circular, however modern North American cards have typically standardized on a 2.5 by 3.5 inch (6.35 cm by 8.89 cm) rectangular format.
The first hockey cards were included in cigarette packages from 1910 to 1913. After World War I, only one more cigarette set was issued, during the 1924-25 season by Champ's Cigarettes. NHL player Billy Coutu's biography includes an example of one of the 40 cards issued at that time.
During the 1920s, some hockey cards were printed by food and candy companies, such as Paulin's Candy, Maple Crispette, Crescent, Holland Creameries and La Patrie.
Through to 1941, O-Pee-Chee printed hockey cards, stopping production for World War II. Presumably, the 1941 involvement of the US in the war affected the hockey card market, since Canada had been in the war since 1939.
Hockey cards next appeared during 1951-52, issued by Shirriff Desserts, York Peanut Butter and Post Cereal. Toronto's Parkhurst Products began printing cards in 1951, followed by Brooklyn's Topps Chewing Gum in 1954-1955. O-Pee-Chee and Topps did not produce cards for the 1955-56 season, but returned for 1957-58. Other companies to manufacture hockey cards include Pinnacle Brands, Pacific Trading Cards and Pro Set. Esso briefly issued stamp-sized hockey cards on soft paper in the early 1970s in return for gas purchases.
Post lockout hockey cards (2005-present) 
After the National Hockey League lockout that wiped out the 2004-05 NHL season, the hockey card market changed dramatically. Prior to the lockout, Upper Deck, Pacific, Topps and In The Game Trading Cards were all licensed by the NHL and NHLPA to produce trading cards featuring NHL players and logos. After the lockout, Upper Deck emerged with an exclusive contract from both parties. Upper Deck paid $25 million over 5 years for this deal with the PA. Without licensing, Topps simply did not produce hockey cards. Pacific went out of business, its last set was produced just prior to the NHL lockout. In The Game continued to produce hockey cards without NHL and NHLPA licensing. They signed current and retired NHL players to individual contracts, allowing the use of their likenesses and autographs. In The Game also signed licensing deals with the CHL, the AHL and Hockey Canada to use players and logos from these organizations in their products. Prior to the 2010-11 NHL season, Upper Deck renewed its license and the NHL and PA awarded Panini with a license.
