Steel Time Capsule for 2056 A.D. (1956)
In 1956 the American Iron and Steel Institute placed a time capsule inside the cornerstone of an office building at 150 East 42nd St, New York City. To mark the occasion the Institute took out an advertisement in newspapers throughout Steel Country. This version of the ad was found in the October 30, 1956 Lebanon Daily News (Lebanon, PA). Stay tuned later in the week as we examine the contents of this time capsule, which is to be opened in 2056 A.D.
