Hello all, I've got a poster which I need some information on please. It's a 1977 style 'C' Star Wars poster. It's not in great condition but I've started looking into getting it restored. My grandfather worked in a cinema in the 70's in London and used to bring posters home for my elder siblings. I remember this being on my brothers wall and rescued it before it was thrown away. I collected toys and vehicles until I was 16-17 and totally forgot about the poster. I've recently picked up my collection from my fathers house and found it inside an AT-AT box! I'd like to know the valuation as it is now, and once it's restored please. Many thanks.
