(re: re: re: re: re: re: Kinko’s scanning) Never had any Interaction magazines myself… wasn’t aware of them in the UK?!
The guy who runs the Vintage Sierra site had posted some mag covers a while back (last years). His scans are of the covers and they are generally <300K each and ‘around’ the size you requested.

IMO, the quality presented is still very useable 🙂
