Sing Your Life
Maybe you know if they were repro'd or not?
It is hard to tell with old show posters. From first glance it looks like an original. What I have done with old tour posters to see if they are original is letting my picture framer take a look at them to see if the paper is from the era in question. They usually charge a few dollars but I find it is well wrth it as the tests they do seem to be spot on.
I still cannot get over all your posters...they look sooo beautiful on the walls.
