These are the effects storyboards for the episode End of Eternity. The story has few effects shots- just 10 scenes are storyboarded over 3 sheets.
Scene 2.
Moon + asteroid
Designed to be similar to scene 80 (see below), instead we see a closer shot of the asteroid against stars.
Scene 4.
Eagle on asteroid
In the main drawing, the Eagle is on flat ground, but in the smaller sketch the Eagle is on a slope. The actual shot changes the angle.
Scene 18.
Eagle twds Moon. 18 m/m. 11" Eagle.
As the comments note, the small 11 inch Eagle is used for the shot.
