Wojtek Siudmak (b. 1942) is a highly prolific Polish sci-fi surrealist painter, primarily of book covers and album art. Across the last 50 years, he’s produced staggering number of works. In fact, if you’re a reader of science fiction at all, then you’ve surely seen his paintings before. (The Internet Science Fiction Database has a fine catalog of his book covers and interior art going back to 1970.)
Siudmak’s style is comfortably in the “sci-fi surrealist” tradition, similar to the Dutch painter Karel Thole. His fantastic, otherworldly, often godlike subjects stand on broad planes or other expanses which give his covers a sense of depth and space appropriate to the subject matter.
