"Mechanical Design Methods" - Complete Set (Volumes 1 & 2) Yoshio Ogawa Published in Showa 40 (1965) This is an old item, so there is some yellowing and wear. The back cover of Volume 1 and the slipcase have some tears. There is a handwritten date of purchase on the last page of Volume 2. Both volumes have significant yellowing on the first and last pages, but are in relatively good condition considering their age. Please consider this with the above in mind. #YoshioOgawa #Books #Electrical/Mechanical Engineering"
