Rare Spanish Eagle Paperback Book

This is a rare paperback book from Spain. The book is titled The Black Eagle. This paperback is wrote in Spanish and has various photos from the film from The Eagle from 1925. The book is made with a cheaper paper stock which means most likely there is not a great deal of copies still in existence. This book is very difficult to find and would be quite valuable. I am a huge Valentino book geek this was a fantastic book to obtain.
