I contacted Keith McCaffery at the Wisconsin DNR and he stated the following:

Dear Rich,
I think that I have shot one or more deer with bow and gun every year since before 1982 and I don't recall ever seeing a harvest pin. However, Wisconsin Bowhunters did have annual membership pins. WBH also awarded year-specific patches/pins for successful archers. I still have several of the pins (1975-1985) in my desk and a gun cabinet full of patches. I do not know if WBH still issues pins with a membership.
Cheers, Keith
