This button was sold on individual cards as well as store display cards holding multiple examples. The piece was produced by "Evans Novelty Co. Chicago." There are at least three versions in terms of the construction although front graphics are essentially the same on each. This was the first version. Curl also includes the words "Pat. Applied For." On this version the die-cut tin head and chest of Hitler is a piece of cut-out metal with a tiny tab on its reverse through which a thin wire is inserted. The other end of the wire is held by a pair of equally tiny tabs which are just barely visible on the front of the button to the left of the text panel. The red string is tied around Hitler's neck going up through a slot on the right side of the button and then into a hole in the area of the tree design then back down the reverse of the button and the cord comes out at the base of the tree on this example. Later examples were simplified and have a tab extending along the left edge where the string is tied and this moves the reverse piece up and down. When the cord is pulled Hitler's head rises from the slot as if Uncle Sam is hanging him from a tree limb. Text panel reads "Let's Pull Together." String "hangs" Hitler but he needs a push to retract back into the slotted area. Outstanding NM paint and this version is particularly scarce. Comes with Hake's COA.
