“Neviditelný (Jaroslav Havlíček) is a Czech novel by Jaroslav Havlíček. It was first published in 1937.”
A quick google search tells me. I discovered that most of Jaroslav Havlíček’s novels are psychological, generally focusing on young men and women and their relationships in extreme conditions. I have no idea what this specific novel is about, alas this art work is too striking to not share.
