Images found in two 1980s books, Naoyuki Katoh SF Illustrations I and II (there's also a volume III), which I occasionally have for sale at 50 Watts Books.
Naoyuki Katoh, Voyage of the Space Beagle, c 1980s
(Find me at 50 Watts Books.)
Here's a real find (for me at least): an illustration from a 1925 issue of Kodomonotomo. I had never seen work by this person (I think I'd remember!): Kozo Yokoi (1889–1965), who went on to a career as a painter (dubbed "the Japanese Rousseau"). I scanned these from a 2017 book on Kodomonotomo. I'll see what else I can dig up.

A Tiger in the Land of Dreams is the first English-language edition of a legendary picture book from 1984. Tiger Tateishi, well-known in the worlds of art and comics, takes us on a journey through a surreal land with Torakichi, a constantly-morphing green tiger. The artist saw this strange tiger as a combination of an animal and a plant. Suitable for all ages, but this is the type of book you buy for the dreamy artwork.
