The cover of Tales From Space looking very familiar.
Tales From Space was a comic book read by Sherman Peabody in 1955. The story was apparently about hostile aliens coming to Earth from Pluto. It was in Sherman's possession when the DeLorean time machine slammed into their barn.
The cover of the comic book showed a spacecraft that looked very similar to the DeLorean, as well as an alien in a yellow suit just like Marty McFly's radiation suit. Sherman also believed that the spaceman had mutated into human form when Marty took off his helmet.
Behind the scenes
Tales from Space was not a real comic book, but rather it was a prop created specifically for Back to the Future by Andrew Probert, the movie's production illustrator. Though essentially fake, it was strongly based on real comics released by EC Comics in the 1950s.
The comic book has since appeared in many works of fiction such as 3rd Rock from the Sun and Heroes.
