Vintage Football Growl Towel Browns? Grizzly’s? Bobcats?

This growl towel is in great shape! It measures 20”x15 1/2”. It does have a couple of small dark spots here and there but they may come out in the wash and they are very faint! I’m not sure if this was from a team sport or what! No rips, popped holes, or stitches coming undone. The tag says “ milum textile services”. It’s a Terry cloth towel for sure!
