Incredible photos. I wish the bunker had survived so Conrad could use his "better technique" and show us what it looked like now. I can almost imagine Hitler and his acolytes using the rooms that were photographed.
This guy snuck in as a construction worker when it was opened up and mostly demolished by the East Germans. Alot of his film got confiscated but he held on to a few and Der Spiegel published them. Don't know if it was posted already, but the article is recent. http://www.spiegel.de/international/germany/secret-photographs-of-hitler-bunker-in-berlin-by-robert-conrad-a-903750.html
