This is an incredible background. I love the fact that you can see the entire spaceship at one time. I scanned this image with the B-18 cel layer missing. All it included was a bunch of steam around the base of the spaceship, and I prefer to look at the entire ship unobstructed. There is also supposed to be an additional layer that shows the opening doors. As you can see from the merged screen captures, they are brown with a tan grid pattern on them. The missing layer is obvious since you can see the unpainted gap between the lighter background and the darker foreground. Hopefully, I will someday be able to get the missing door layer. I have been surprised at how lucky I have been over the years in this regard.
