Roy Lichtenstein "Hommage To Picasso" Original 1973 Berlin Exhibit Poster

PLEASE READ UPDATED DESCRIPTION
Original "Hommage To Picasso" exibition lithograph print poster from Berlin, Germany in 1973 with printed dot matrix signature by famed pop art artist Roy Lichtenstein. Not his signature just a copy of it. There are several Hanover, Germany posters online but mine is the only Berlin copy. Shows some signs of brown spots & yellowing due to the age but for the most part its in great condition with no tears.
Please feel free to ask any questions.
