In 1988, there were a lot of Cubs sets that met this description, as will be seen in this post. Broder's features athletes who are currently employed by a professional sports league. Ed Broder and his son Rob, who worked as freelance photographers at big league games, didn't pay a licensing fee. Broder cards have zero value as an investment. By the middle of the 1990s, MLB had shut down these sets and permanently banned Broder cards.
Most these set have one Cubs player
