NEW YORK (Reuters) - A rare, original poster from the Boris Karloff horror classic “The Mummy” that was predicted to set a record price for a film poster at auction went unsold on Wednesday when no one bid the $950,000 minimum in the online sale. Sotheby’s had predicted that the work, one of only three known surviving examples of the original lithographic poster from the 1932 film, would fetch up to $1.5 million.
