Great photo showing a 10-port switchboard with a dialer. Top-left you can see a Volksempfänger, a radio clock to the bottom right and the sign "Vorsicht! / Feind hört mit!".



A very nice photo showing a Luftwaffe telephone operator with a stacked switching console, three dialers, three phantom boxes, a speaker and a communications clock. He is also wearing a chest mike.



Someone decided to produce some "telephone art". I guess there was time to kill that day.
