The jumper is a genuine vintage Stussy item from 1992/93 and was bought in Camden Market. 

There is a large Stussy tag logo on the rear and a smaller one on the front.

There is a small mark on the back of the jumper and it the logo has faded a little due its age. 

Please note that as this is an XL, and as it is from the early 1990s is a baggy fit in the body and the neckline is wider than more modern items. 

Thanks for looking!
