"The man who won first prize at the surrealists' ball."  From Nebelspalter, 1930.

These surreal CAPTCHA puzzles!  I can't click "verify" without selecting an image, yet they're all not pipes.  It's a Catch-22 (er, CAPTCHA-22?) situation.  A robot can't be in a Catch-22, so I've proven I'm not a robot, yet I can't submit my proof.

Yeah, we've been to that door.  It was locked.  From Unknown, 1942.

What exacty is happening here?  Well, "It's always happening more than it ever has been happening" (The Mammoth Book of the Rolling Stones).  "It's always happening.  But be still now!  They're coming up, and all we can do is to keep them in the dark as well as we can" (William Dean Howells, "The Unexpected Guests").

René Magritte's "The Son of Man" (1964 ) finds a precursor in the bumble bees of the Kashmir Himalayas.  Our image (left) is from 1954 and appears in the Bulletin of the British Museum (Natural History) Entomology.  It goes without saying that "Apples depend upon bees to pollinate their flowers so that the tree will develop fruit."

From Bell Telephone Magazine, 1972.

A duck-headed butler opening the door for a Poe-esque gentleman?  Check.  (By the way, that's a precursor to David Lynch's commercial for the Sony Playstation, in which a duck says, "Welcome to the 'third place.'")  A faceless figure surrounded by disembodied cackling faces?  Check.  A crow in a jacket standing on a meditative sheep while an anthropomorphic dice cup spills and kills an innocent bystander?  Check.  A skeleton holding the Ace of Hearts?  Check.  Edward Gorey-esque despair on a settee?  Check.  Granted, the figure blowing his head off does seem rather too much.  From Judy, Or The London Serio-Comic Journal, 1884.

This is not a pipe.  From Fun magazine, 1864.
