The Super 70's set has an insert set called Happening Hairdos. As soon as I saw that, I thought that there is one Cub that would be perfect for that set. Think 1970s Cubs and hairdos and you may think of the same person.
Topps did not. They thought of Bruce Sutter. I don't see anything that I would consider "Happening" with Sutter's hair.
I made a card for the player that I, along with any Cub fan from the 1970s, thought of.
Jose's afro was super-happening! How is it that he wasn't a part of the set?
