This is a dual book in English and Spanish. So if you print it “two pages per sheet”, you will see the left part of the page in English and the right part in Spanish.
Nice way to learn, either English or Spanish.
The book is a classic: “Animal Farm” by George Orwell who is one of my favourite writers.
Enjoy it
