There are many Popular Photography issues available on Google Books. Mostly from 80s and 90s. My favourites are the December issues with the "199X Top Cameras".
E.g. Pop Photo Dec 1996 (mostly full page) camera profiles of:
Canon 1N
Nikon F5
Minolta 9Xi
Leica R7
Contax RTSIII
Olympus OM4-T
Nikon FM2
Contax G2
Leica M6
And more! I'm keeping an eye out for the print versions of some of the issues.
