Introduction
In October 2025, going through some old boxes of documents, my wife found a trifold made by IBM explaining their display at the 1964/5 World's Fair in New York. Her family took her to the World's Fair in 1965, aand she remembers seeing the "egg" building IBM built but nothing else about it.
The Trifold

The back of the trifold explains IBMs dsplay:
Welcome to the IBM Pavilion
In the garden-like atmosphere of the IBM Pavilion, you will find pathways that will lead you through a man-made forest to fascinating world of computers.
Here are some of the highlights you won't want to miss. The map on the other side shows the location of these features.1 People Wall and the Information Machine
The elevated walkways will lead you to one of 12 rows of seats on the "People Wall." When you are comfortably seated, the entire Wall will rise-in full view of Fair-goers on the ground. The Wall will carry you up into the huge elevated theater, "The Information Machine," which rises 90 feet above the Fairgrounds. "The Information Machine" is a 15-minute spectacular of sound and sight, coming to you from 15 separate screens.
Your host explains that this is really an information machine-because it is a way of telling you quickly and vividly all sorts of facts. As the action unfolds, you'll see how the method used today in solving even the most complex problems is essentially the same method we all use daily.
You'll see how a football coach planning a pass play goes through some of the same logical steps as an engineer testing a model of a rocket-plane... how a hostess planning a dinner party develops a model to solve her problem, just as city planners studying the many facets of a large city develop a model of a mucl1 more complex problem for a computer to solve.
Through dramatic examples from the everyday world and the world of science, you'll see how computers are used to solve the most complex problems in much the same way people use simple logical steps to solve ordinary problems.
The show-produced by Charles and Ray Eames, with story by Glen Fleck and musical score by Elmer Bernstein-is an experience you'll be talking about, and thinking about, for a long time to come.
2 Computer Court
How can a machine translate from one language into another? Watch as a typist feeds complex Russian technical reports into an experimental computer-and see a simple but understandable translation appear almost immediately on an automatic printer.
Can a computer "read" and "understand" your own handwritten birthdate? Try it-and take home a souvenir printout of a New York Times news item that appeared on the day you selected. Almost 40,000 headlines from the last 113 years have been stored in the computer's memory ready for instant retrieval.
3 Probability Machine
Watch as thousands of plastic balls cascade down through a 15-foot high pinball maze.
Each ball can land in any one of 21 chutes at the bottom of the machine, yet each chute will fill to approximately the same height each time the balls are released. These experiments repeatedly test the Theory of Probability.
4 Scholar's Walk
Want to relax a bit before heading for the Little Theaters? Try the "Scholar's Walk"-a secluded area that will entertain you with fascinating stories about mathematical concepts and the development of computers.
5 Little Theaters
In the center of the garden are animated theaters featuring puppet-like devices that help dispel many mysteries about the world of computers. In one theater, for example, Sherlock Holmes unravels "The Singular Case of the Plural Green Moustache," using the same kind of logic that computers use-and that you use in solving everyday problems.
6 Typewriter Bar
Just about everyone who visits the IBM Pavilion sooner or later ends up at the circular typewriter bar. Free postcards are provided for anyone who wishes to try an IBM Selectric typewriter, a uniquely different machine that has no moving carriage.
The shows are continuous in the IBM Pavilion and everything's free. If you have any questions about anything you see at the Pavilion, a member of the IBM World's Fair Staff will be glad to help you.
I have scanned the IBM trifold and made it available for viewing and downloading.
