I recently saw and won an auction on eBay for two Amiga posters from the 80’s. One was a “2010: The Year We Make Contact”-themed poster (popular movie, 1985 I believe) and the other is an Amiga Developers Conference poster featuring a scene from the famous early Amiga app, “RoboCity”.
I grabbed them from a Commodore ex-employee and had the latter framed and hung it in my new basement computer room.
Good stuff!
