Nightwings, original book cover illustration 

Don Ivan Punchatz was a prolific American illustrator known for his work in fantasy and science fiction genres. His art for the book cover "Nightwings" features a crescent moon with a human-like face, a large white wing, and a figure with outstretched arms. The scene is set in a mystical, almost otherworldly landscape with columns and arches reminiscent of ancient ruins, indicating the fantastical, even surreal nature of the artwork. Punchatz's art often incorporates elements of magic and the supernatural. He achieved popularity in the 1970s for his work in the field of science fiction and fantasy, and for his contributions to the cover designs for popular science fiction magazines of the time.
