I was surprised, too, that this film was from the ’50s. Then again, 1958 and ’59 are somewhat honorary members of the ’60s, since that’s when angular design elbowed out the curves and bulbous designs that came before.
I agree about the awful ’70s. I really, really, try to be open to all sorts of design, and to appreciate things for their own peculiar aesthetic. But something about the ’70s looks really dreary to me. I remember that decade as one of conflict, economic failure, and macrame. Earth tones were popular, and the only bright colors seemed to be garish eruptions of red, white, and blue (for the bicentennial, of course). The other reason the ’70s don’t get much love is that they were the decade when unapologetic cheapness started creeping into production decisions. It worsened later, but it certainly began there.
