International Space Commerce: Building from Scratch Book

I thought I was eventually going to have to pay an antiquarian book dealer in blood for a copy of this book, but I stumbled across this reprint edition at the Pima AFB museum. This is the book that changed Arthur C. Clarke's life- the first serious English language text on the prospects of manned spaceflight. Lasser lays it all out- a mandate for the exploration of the solar system that reads like a historical document in light of the progress that has been made in the seven decades since it was published.
