During the late 1940s, after the second bomb fell on Nagasaki, the concept of the atomic weapon was largely perceived as the tool of victory that "ended World War II." Censured from the brutal reality and the human cost of what had occurred (the only available imagery of the disaster didn't appear until the 1970s), Americans memorialized and glorified the mushroom cloud in Hollywood movies, corporate branding and logo design, advertising and even pastries for upscale dinner-parties.
