Vintage Biology Second Edition 1965 - Kroeber, Wolff, and Weaver hardcover book

Biology, second edition. Copyright 1965. Authors were Elsbeth Kroeber, Walter H Wolff, and Richard L Weaver. This book was sent to Melvin Kenneth Nystrom from D C Heath and Company publishers for consideration as a text. I, being an avid genealogist, have included his obituary for your perusal. He had a degree in Education, I am guessing a science teacher? Always interesting to have the story with the vintage piece. Anyhooo. Book is in good used condition, with some wear to cover.
