Gaia Gear is a novel set and radio drama set in the future of UC in the Gundam universe. One of Tomino's early visions of the future of UC, now invalidated by later work and rapidly being pushed far into the background. Here are pictures and mobile suit lineart for a lot of the Vehicles, mecha and weaponry in the tale. I found about half of them on Japanese imageboards, the other half were sent to me by Havail
Maserec and Neo-Era. Click on the pictures for a larger version.
