The "GI Script" I brought home with me. It has autographs of several of the guys from the battery. That is what we used for money and periodically it had to be turned in and a new style was issued. That was to keep the civilian black marketers under control because civilians could have only a maximum amount. Lots of GIs made megabuck profit on the exchange because civilians would find out about the upcoming exchange (although it was supposed to be unannounced) and unload their hoard at pennies on the dollar.
