Recent addition to my aviation library. Tin reproduction ad of Interflug, national flag carrier of The German Democratic Republic, which I found at "regular" book store. Interflug was liquidated in 1991, in parallel with the collapse of the GDR government, and couldn't celebrate year 2000. Berlin Schönefeld Airport, their base, shown at the bottom is now being transformed into Berlin-Brandenburg International Airport which is planned to be opened in 2011 as a new gateway of Berlin for the sky.
