Gorgeous design borrowing from a few different properties, including Star Wars, Buck Rogers, and 2001. The distant city is my favorite, and the coloring is perfect. The landspeeder’s shadow is a nice touch.

It’s just not the ’70s without brown, burnt orange, and pea green.
Awesome find. I like how they upgraded the Landspeeder with a hood-mounted laser cannon.
