Photo of the interzonal train on the route Leipzig-Gutenfuerst-Hof-Munich. This train was known for its "all-German" dining car, which was popular due to the 1: 1 exchange rate, especially among East German travelers. Photo of a lady wanting to order Coca Cola from the waiter. However, since the administration of East Germany prohibited the sale of American products in this dining car, the drink was also unavailable. The billboard hangs there anyway.
