Many compiler related books take inspiration from the "Dragon book" (Compilers: Principles, Techniques and Tools). So with likely lots of books with similar looking covers.
Point was more that there are bunch of compiler related books featuring a dragon (and knight/other character). The original also has a different looking dragon & knight themed cover for every edition.
Like if I’d see the book on a shelf I would instantly guess it’s related to compilers. And I bet that’s completely intentional homage to the original.
