For my money, no magazine is a better time capsule of 1970s living than Apartment Life. The magazine eventually became Metropolitan Living in 1979; a glossy coffee table magazine with no character. But for a few glorious years in the 70s, Apartment Life perfectly encapsulated the culture, the fashion, the look and the feel of the time.
I've scanned a few pages from the May 1977 issue (and I've posted another issue here), but nothing can take the place of sitting down and reading it. Priceless.
