This is a great puzzle only diminished by a lack of editing. Each picture shows a “present/not present” state to represent either raised bumps or absent bumps respectively. Yet for the egg, windows, and drawer pictures this logic has been reversed. Fortunately it is still solvable assuming this was merely an oversight in consistency, but for a book with such a high calibre of puzzles I would have expected this not to have slipped through the editing process.
