This was taken from the home of my deceased Uncle. I am assuming it is a textbook of his. He went to the Texas School for the Deaf I Austin Texas. It is still in fair condition and attached at the binder. It is a supplement book to a chemistry book. It has definite signs of discoloration on cover and pages but is still fair condition. Look at provided photos. There is a glossary and a sample test in the back. Some pen markings with name inscribed on cover.
