These cels came from a person who worked on the Dinosaucer toys in Galoob. It seems the animators sent this drawings of the vehicles and ships to show concepts to the toy sculptors. The ships here are all ones that were never sculpted. Galoob was setting up for a hit toyline and was preparing the 2nd series. These cels are as far the ships and vehicle series got. There might be some concept art or schematics out there. Enjoy!
