For all you Star Wars fans out there. Darth Vader signing a Raw Deal movie poster at the opening of Mr Flicks video shop in Bryn. Not sure of exact date, I believe it was 1988 or 89. Would love to know if anyone knows what year and month this was and any other info would be appreciated.

I remember there being a newspaper article about it in the Observer (I think), with a photo taken outside the shop with him and a crowd of people; I remember having a copy of it but don't think I have it anymore. Just wish I still had that signed poster.
