The Promise: It only cost a dime and you could feel like those engineers at NASA or the next Neil Armstrong while building this scale model with "30 precision parts" and "two lunar astronauts in FULL space gear." Plus, you'd get membership into The Science Program, which would entitle you to a 25-part science album that was different every month and covered various topics from space to mechanics and photography. The guidebook was illustrated and came with a number of full colour photos.

The Truth: Well, a scale-model meant you were only flying to space in your dreams, but that Science Program membership was real. No word on the quality of the albums, or whether readers really got them in the first place.
