Please find below images taken from the April 7, 1961, SCIENCE magazine which has been footnoted on the cover in his handwriting. This example was Harvey Nininger's personal copy, and I'm pleased to offer it for auction via Maria Haas at IMCA as another fundraiser benefitting our fellow member, Gary Foote.
Nininger frequently referenced SCIENCE magazine in his books (for just one example off the top of my head, please see the bottom of p. 189 in Find A Falling Star).
If you have any questions, please
contact Maria Haas, and thank you in advance for helping support the Footes in their time of need (all proceeds obviously go to them).
