This book introduces you not only the hieroglyphics of the Egyptians but also those of the Mayans and Aztecs. Teach Yourself Hieroglyphics presents the development of writing, Egyptian grammar, and the Mayan calendar. In addition, the book includes blank cartouches to practice drawing your own hieroglyphics..
Not so bad for starters, but unavoidably superficial and somewhat scientifically controversial. So better consider reading Gardiner if interested in Egyptian.
