The only deck I can remember from the days when I was a hippie is the Albano-Waite. Of the decks I own now, I'd say the Pearls of Wisdom and the New age (Neuzeit-Tarot) both look to be drawn by artists who drank the electric Kool-Aid.
Ah...yes...the libation of the gods...
And where's the Beatles tarot? Eh? High Priestess: Lucy in the Sky... The Fool on the Hill...
