From reading this I think your T-shirt is not a bootleg at all...no it's a T-shirt!
http://dustfactoryvintage.com/screen-stars-about-the-label/Read the Beatles T-shirt comment too, as theirs was made in Ireland...and an expert in their field wreckons it was made in the 80's. All in all I think your T-shirt is authentic, but then again I've only spent a couple of minutes researching it.
