N.O.S. Karlsson "time talks" xxl flip clock. This clock has not been for sale for years, but I acquired a few from a warehouse. This clock is really a giant, measuring 80 x 16 cm! Great to see how every 5 minutes the signs with texts flip over and indicate the new time in text. Again: this clock is really big! I also have a French version if necessary. The clock runs on batteries or a universal power supply. These are both included. A unique opportunity to purchase this example of design technology.
