There are a number of similar postcards on ebay now, representing the Padres, Mariners, Blue Jays, Yankees, Cubs, Braves, and Expos. Most of these auctions are by Fritsch cards, and their listings state "The postcards in this collection feature the artwork of noted photographers Mike Anderson, George Brace, Ed Broder, Jeff Morey, and Norman Paulson among others."
