From Psychological Monographs, 1921.

Brockton Fair, 1933.

Here's the Queen of the 25 of Spades, c. 1905, scanned by the National Library of Ireland.

"Instead of construing these five as distinct selves, I take them to be five aspects of the self, forming the multitudinous self" (Serife Tekin, "The Missing Self in Hacking's Looping Effects," Classifying Psychopathology: Mental Kinds and Natural Kinds, 2014).

Here's the acclaimed lawyer Clarence Darrow (left) and someone not acclaimed (right), photographed by Leslie Jones (as scanned by the Boston Public Library).

The great secret of weathervanes is that they alter the direction of the wind they measure (as per the "observer effect" of physics).  Here are two weathervanes with conflicting reports, as photographed by Leslie Jones, date uncertain.  And then here's another photo of disagreeing weathervanes, not that you didn't believe us.  Plus, it's not just weathervanes: flags also flap according to conflicting winds (photo our own).

"Note that all six zeros are complex" (Proceedings of the Fifth New England Bioengineering Conference, 1977).  Photo by Leslie Jones, 1928.

"The Dissolution of the Government.  One of the most mystifying and amusing trick films ever produced."  From Moving Pictures by Frederick Talbot, 1914.

"Help help!!  Please do not kill these or bacon will cost you one dollar a pound."  Photo by Leslie Jones, date uncertain.

"Puritan statue pulled down by Harvard students in Cambridge Common."  Photo by Leslie Jones.

This damaged photo appears to have a boat floating in the air with its reflection.  Click to undamage the image and lower the boat into the water.  (But don't ask us how we did it!)  "Watertown, Charles River, Perkins Institute for the Blind."  Photo by Leslie Jones, date uncertain.

Eddie Loos once said that "there are two sides to golf" (The Best Advice Ever for Golfers), but "to look forward from the other side is terrifying" (Glenn Smith, Aesthetic Wilderness).  This photo of the other side of golf, by Leslie Jones, appears exactly as it was scanned by the Boston Public Library.

"My mistake, April 12, 1925."  Live to photograph it.

An airship in a damaged photo … or is this what really happened to the Hindenburg?

William Beveridge, c. 1930s.

(Our quotation for this collage appears in Jay Sherman's Action Manifesto of a Madman for Good, 2013.  Photo by Leslie Jones, 1935.)

People often ask "where are the flying cars we were promised?"  The answer is that we've always had flying cars — they simply failed in the marketplace.  It's easy to state what we think we want, and it's easy to daydream, but acting upon our desires makes all the difference.  Thanks to the San Diego Air & Space Museum Archives for scanning these and several other models of flying cars.

"Do we see ourselves in others?  Do we look back from outside and see ourselves?  Do we see growth and expansion?  Do we see our greater self?" (James Anderson Charleson, Experience Personal Fulfillment, 2013).  Our photo of someone seeing her greater self in another is an "overlay of images of Amadeo and Lucie (Portugal, 1915)."
