Hi wonder if anyone can help - i have a Death Wish Charles Bronson - Herbie Hancock score film poster by M.A.P.S Litho ptg ltd. It has a black Capital 'R' surrounded by a tilted square border on the front near bottom right corner. Does this signify a repro or is this the certificate it was given? Thank you.
