Here's the print: http://imgur.com/gallery/7pf4U
It's obvious the page has been ripped out of what I'd guess is an old magazine. The page is the size of an old school Life Magazine but I'm not sure how to confirm that that's where it's from. The back includes part of an article about 1968 Olympians and references 1974 as upcoming, so I'm assuming the 1973 on the dove art is a correct representation of the print year. I've google image searched the entire print, as well as the individual artworks and... nada. Even researching the artist names don't pull up any of these individual pieces. The Japanese artist's name doesn't pull up any results at all! Would love any tips on how to figure out this print's origin.
"Satire in the Fight for Peace" was a series of international art exhibitions; the individual artworks you're looking at are samples from that '73 exhibition - if you look in the Sputnik Images archive, the picture of the dove and the tank by Mituga Katayeri is from the 2nd International Exhibition, held in 1973.
Unfortunately, that doesn't particularly help find the source of this particular page. It can't be a regular issue of LIFE magazine, because LIFE didn't publish regular issues from 1973-1977, only resuming regular publication in 1978! LIFE did publish special YEAR IN PICTURES issues during that period, however, and I'd probably start there.
