This is an original concert T-shirt from Julian Lennon's 1985 tour Valotte. 

It is a Screen Stars 50/50 cotton polyester blend in a Medium size.  It measures 18 inches under the arms and 22 inches from the collar to the bottom in the front. 

There is a small mark about 1/4 inch that I have not tried to wash. It is next to the 'J', please see pictures.  There are no holes or tears. 

Thanks for looking!
