Sin duda, si el objetivo es disfrutar con ilusiones ópticas poco frecuentes, el libro de Richard Block incluye numerosos ejemplos, algunos muy antiguos, relacionados con el género. Parte del material no es fácil encontrarlo en otros libros como los sencillos pero eficaces dibujos dobles de G.H. Fisher. Muy recomendable.
