Joseph Sullivan, in his fine site, which is replete with comment and reviews of book designs, points out that Penguin is having fun playing with the company colophon.
I surely do agree that the jacket of The Penguin Book of Gaslight Crime is beguilingly whimsical -- and those pencils are mind-bending. Wow!
The name of the designer of the Gaslight Crime book is unknown. Coralie Bickford-Smith dreamed up the jacket for The Craftsman, and author Richard Sennett must be mightily chuffed. Joseph Sullivan declares he is a Bickford-Smith fan, which is no surprise at all.
