This is a Hardcover Catholic Textbook - Copyright 1945

Book is in good general condition - some yellowing of pages, but pages and binding are tight. Boards have some rubbing and shelf wear. 

Fully illustrated with both black & white and color illustrations

I purchased this from the estate of the previous owner, who attended Regis High School in Denver in the 1940s and wrote his name and address on the title page of the book (as shown in the photos, there are a couple of other places where the previous owner also made little "tic marks" on a couple of the pages).
