Currently on EBay is a vintage piece of artwork that depicts – apparently – a robotic Mars lander probe. it looks a lot like a cross between Surveyor and Viking; it *might* be an advanced Voyager design (from when Voyager was a Saturn V-launched Mars mission, before it was a Titan III-launched outer solar system mission) from the late 1960’s.
Interesting. Definitely a very nice painting.
The painting was clearly copied from the December, 1967 issue of National Geographic Magazine in an article about Mars by Carl Sagan. Here is the original artwork:
