Quantum Mechanics, by John L. Powell and Bernd Crasemann. Hardcover book, c. 1965; Stated Third Printing, May, 1965. Pages are in very clean, good condition! I don't see any writing or highlighting (though I cannot guarantee that I didn't miss any). There is just a spot on the inside front cover where a name was clearly erased. Please see all the pictures for more details. This book comes from our smoke-free, pet-free home. Thanks for looking!
