An interesting pulp scifi picture book from the 70s. It comes in 3 parts: Scifi paintings ranging from realistic cityscapes to fantasy art in the realm of album covers, simple essays about the history of scifi, and a sort of worldbuilding series of short fiction pieces where they take maybe one in 5 of these widely varying unconnected different art pieces and tie them together as though they all belonged to the same universe, including a few cross section/exploded mechanical drawings of some of the artwork.
Basically, it's a bit of light reading soaked in the aesthetic of 70s scifi, with a lot of fondness for spaceships and robots.
