An IBM newsletter or handout dated February 2, 1972, announcing an exhibit highlighting the Eckert's work at the IBM Display Center, 590 Madison Avenue in New York City, 24 January - 17 March, 1972. The handwritten notations ("The following table shows the old and new constants of inclination...") are apparently Eckert's. The exhibition was designed and mounted by Eames Office: "This Eames Office exhibition paid homage to Wallace J. Eckert, an astronomer who worked with IBM as early as 1944. He advanced astronomy by involving computers in the study of the complex motions of the moon, celestial navigation, and star mapping. The three sections of the exhibition, 'Air Almanac,' 'Lunar Theory,' and 'Astronomy,' included memorabilia, samples of Eckert's research materials, a timeline of his career, and text and photographs to contextualize his work. Wallace J. Eckert: Celestial Mechanic first went on view in 1972 at the IBM Corporate Exhibit Center in New York, before traveling to additional venues nationwide" — Including the Smithsonian Institution in Washington DC.
