Bohumil Stepan’s illustrations for Gulliverovy Cesty (Gulliver’s Travels), Prague 1968:
surely Haeckel in the background
“Max Ernst and Saul Steinberg meet Jonathan Swift in Prague.”
I haven’t found much info on Bohumil Stepan (1913 – 1985), though based on his style I’ll guess that he and Adolf Hoffmeister (1902 – 1973) were from the same circle of artists. I hope to hunt-and-gather more of his books soon.
