RARE Bruce Springsteen Live in Panama Concert Tee

I've searched high and low and CANNOT find this Bruce Springsteen concert band tee t-shirt anywhere. It appears to be for a fundraising concert LIVE IN PANAMA - WE CAN MAKE IT HAPPEN with a donation address on the back for the "Born in the USA Committee" in Miami. It includes the printed signatures of two people, presumably from the fundraising gig. Great Woodstock-like guitar horizontal logo on the front. In good shape. Size listed is as Medium 38-40, but it seems like a Small to me.
