I think this might be the Holy Grail for you collectors. I can't say I've ever seen a Mack cap with ear flaps. This snapback is in EXCELLENT CONDITION.
The foam on the inside is intact and excellent. There are no rips stains soiling, it's AWESOME. There's what appears to be a tag ripped off the top of the cap. It's sewn into the lining.
