If you remember the 70's with fondness, this will bring it all back and remind you why you loved the times so much. The 60's were just the setup for the manifestation stage of the spirit, philosophy, and urge to stretch out, spread your wings and have a good time.
Seeing the trans-Atlantic richness of design accumulated in this very beautiful book helped me see how grounded my own ongoing sense of design is in the 70's aesthetic. Thames & Hudson continues their tradition of providing great art books, good commentary and balance, and juicy visuals.
We needed this survey of what the essence of that decade was. Much of it still looks very Now and if it doesn't to you, the exhuberance and playfulness will make you long for a return. If so, you might enjoy my out-of-print book from 1974, Native Funk & Flash: An Emerging Folk Art, found in the used books section where you can still find a few old copies. (Just look for Funk & Flash.)
