This book by Herbert S. Terrace entitled, "NIM: A Chimpanzee Who Learned Sign Language" was altered by Sackner and Rickles. The dust jacket title was altered to NIMS by Sackner by adding an 'S.' On the dust jacket photograph of NIM, Rickles collaged a piece of the blue Respibands sold by Sackner's company to monitor respiration in babies. She also drew blue Respibands on photographs of NIM throughout pages of the book. -- Source of annotation: Marvin or Ruth Sackner.
