CCCP - Cosmic Communist Constructions Photographed by Frédéric Chaubin

This is the coffee-table book to end all coffee-table books. It's massive and fascinating, both a documentary window into a different world and inspiration for travel. The cover design and title is also super clever, as CCCP looks like СССР (Союз Советских Социалистических Республик) aka USSR.

Read if you like pictures of Soviet Bloc architecture.
