Very Early 80’s Harley-Davidson 3D Emblem (L)

I’ve only seen this shirt 5 times. I own 3 of them (this is one of the 3), the other had cut sleeves, the other was sold for $1100 by a high end vintage shop in Kansas City called Wyco Vintage. It doesn’t get more rare than this. Artwork done by Ty Powell. No tag but it was done on a “sneakers” brand blank like all early 3D emblem just like my other 2 shirts are as well (20” x 27”)
