Understanding Your Diabetes 1978 Pfizer Book

I have "Understanding Your Diabetes" book that was published by Pfizer in 1978. This book is chock full of valuable Diabetes information although some info might be a bit dated. This was my dads that passed away. I thought someone may have a use for it, and or collect old medical information books like this. It does have some stains. All pages are intact, and the binding is tight. I have given several pictures of it so please check those out. If you have any questions please ask.
