This gallery of surreal images is by the Argentine cartoonist, Enrique “Quique” Alcatena from a project called Back Through the Labyrinth (De vuelta al Laberinto). I grabbed these from his blog but haven’t been able to find out much more about the project. If anybody has publication information, please add a comment.
