Early tender prototypes. Siemens cards were a series of Black 20 DM cards, and Giesecke & Devrient were a series of white 20DM cards. A variety of control codes and serial numbers were produced for Deutsche Telekom. This green prototype presaged the Aachen green trials, but with the Black series design.
