Wolves 1970-74 Badge T-Shirt
Wolves had three different badges in the 1970s and five more since, but this one, used from 70-74 is the only one to deploy the WW motif. It was the one they worse when getting to the 1971-72 UEFA Cup Final where they played Spurs (and lost 3-2 on aggregate. Boo)
It's so striking and simple, maybe they'll revisit it someday.
