In the seventies, AMT Model Company decided to create their own space universe, similar to the Star Trek theme. They were to make a series of models, each kit containing a story on the instruction sheet about the ship and a cardboard record which had the "Space, the final frontier..." theme to it. The kit was a failure. Even though it had lights and was designed by Matt Jeffries, the same man who designed the Enterprise, the kits fell flat. The Lief Ericson was the only one made. Later, when the AMT Star Trek line was selling like hotcakes, they reissued it, sans chrome parts and lighting kit. They molded it in glow in the dark plastic and called it the Interplanetary UFO Mystery Ship. It sold better that way, and is being reissued this year as the UFO. I like the design and was a great piece to draw.
