An interesting find

I went to a used book store in Poulsbo, WA today and I was perusing the philosophy/religion section and I came across a book that, in my opinion, is a great find:

On Religion

This book is a collection of works by Marx and Engels with regard to religion. That in itself is enough for me to pick it up, but what really piqued my interest was this:

Printed in the USSR

I appreciate the historical value of this work; a book written by the authors of the Communist Manifesto, and printed in the Soviet Union.
