A 1918 patriotic World War I, Red, White and Blue wooden Safety Cracker that makes a loud sound when the metal handle is turned.  The back has two attached wooden boards that are raised by the metal parts and then they crash down against a larger wooden board and makes a large sound.  The Safety Cracker states

“SAFETY CRACKER, MADE IN U.S.A.,

PATENTED JULY 16^TH 1918”

Not included the 2 inch metal handle sticking out of the side the Cracker is 5 7/8 x 2 11/16 x 7/8 inches in size.  One of the two back boards has a 1 ½ inch crack in the middle which does not diminish the sound made by the cracker.  There is a little wear to red, white and blue colors and overall is in nice condition.  Please see the other vintage items I have listed on eBay.  Thanks for looking.
