Hard to believe, but apparently true, the Gilbert U-238 Atomic Energy Lab was sold in 1951 and came with uranium ore, a geiger counter and other items as shown here. I didn't see any for sale at eBay, but I did find this book on sale at Amazon:
The Man Who Changed How Boys and Toys Were Made: The Life and Times of A. C. Gilbert, the Man Who Saved Christmas
*Previously: The atomic future.
*Buy Vault Boy bobbleheads at eBay.
