There is a set of Encyclopedia Britannica books in the background. Light is coming from the overhead ceiling. The press release on verso side of image reads "YORKTOWN HEIGHTS, N.Y., Dec. 19 ... Computer data was flashed today at 20 million bits of information a second over a 40-mile experimental high-quality television link between Yorktown Heights and Harriman, New York, by International Business Machines Corporation engineers. This is equivalent to transmitting the more than 1,500,000 words in a typical encyclopedia volume in just three seconds. Shown with the experimental system is Dr. Emil Hopner, computer communications manager of the IBM Advanced Systems Development Division. The system uses a binary feedback technique and simple and flexible signal detection equipment and does not require modulation of computer systems for transmission.", "A.E.
