A special limited edition of 50 pieces has been produced for this special occasion, as a gift to the veterans who took part in the 61st meeting of the "509th Composite Group" in Colorado Springs. A special "thank you" goes to John Coster-Mullen, author of the excellent book "Atom Bombs: The Top Secret Inside Story of Little Boy and Fat Man" who has made this occasion possible, and who supported the Manhattan team from day 1 with his deep knowledge of the project.
