World's biggest Halloween parade in New York City seen in surrealistic way, to capture the weird and bizarre necromancy of the Witch's Sabbath and other devilish and unholy apparitions . . . horrific costumes, many carried by groups of ghosts and golblins, imagery of a new and satanic kind, caricatures of politicians, grotesque masks, a grande guignol carnival and spectacle in he middle of Manhattans' Sixth Ave.
