Can you help me with a photo request for a documentary film on the Amiga? I’m trying to track down any imagery from the 1984 Consumer Electronics Shows in Las Vegas and Chicago. I’ve come up with nothing and was wondering if your readers might be able to help?
Answers on an email to firstname.lastname@example.org which will be sent directly to Emily.
