Indeed. I'm not suggesting there's any intention to deceive. Note, though, that the proportions of photograph to the rest of the cover are virtually identical on the two covers. The only stylistic difference is that the Delphi cover has the white strip below the book's title, while the Penguin cover has it above. There's not the least doubt in my mind that Delphi came as close to reproducing Penguin's cover layout as they legally dared.
