Vintage T-Shirt Forum & Community Authentication Appraisals

So Ive been doing endless research on this green Harley-Davidison 'The Bike That Won The War' t shirt. Im only coming up with re-prints from 1990-1997 that are selling for $40. Heres my predicament; for one, theyre all 100% cotton.
Youll see below that mine is 50% poly 50% cotton and has an early 80's screen stars tag. I pulled this out with a haul of alot of other specifically 80's harley-davidson t shirts. So, if anyone could help me with an appraisal, I would greatly appreciate it!

There's an 80s version with a different back in ebay past listings that went for $36. I think 30 to 60 ramge...might get the higher end of that with the SS tag.
