Monte Farber and Amy Zerner, a Springs couple known for their success in interpreting such branches of the occult as tarot and astrology for a mass audience, opened their new shop last weekend in the Village of East Hampton, next to Rowdy Hall in the Parrish Mews off Main Street. At the Enchanted World Emporium, starting tomorrow from 1 to 8 p.m., the author and artist will make available locally all the things they have sold far and wide for many years.
