This book, "Egyptian Grammar with Table of Signs, Bibliography, Exercises for Reading and Glossary", by Adolf Erman, is a replication of a book originally published before 1894. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible.
A grammarian would be so satisfying with the access to this extraordinary instrument... believe me, it's an excellent medium to learn Egyptian language!
