Abstract
A method and apparatus is disclosed for exposing the contents of an envelope which has two opposing panels wherein the panels have been separated from each other along all but one edge portion where the panels remain connected. The envelope is gripped on one of the panels and then the envelope is oriented so that at least the contents of the envelope fall away from the gripped panel to thereby expose the envelope contents.
