Ostalgia
For those of us who are still pining for the long lost days of the DDR, there is this hotel in Berlin: http://news.bbc.co.uk/2/hi/europe/6226946.stm http://www.ostel.eu/ (hopefully you can still pay with Ostmarks)

You can also try this. Das dicke DDR Buch ISBN 3-359-01445-6 Eulenspiegel Verlag Contains all you ever wanted to know about the DDR and a lot you didn't. Regards Bernard Lamb
