I have some Vintage SYNCROS T-shirts,,what do i do with them..!?!?

do you guys think is any interest for them on E-bay or somewere..

I have one of the black "Davinci-Bike" that i never even open from the plastic bag and another one with a picture of some of their cranks...

I keep them new in hopes of someday presenting them on a bike shop i was trying to get togheter, but never got to happend...

actually will be great if you guys and gals show your vintage t-shirt and mountain bike garmets,on this tread.
i really like the grafic design work that when into some of them
