Our public domain collection is free for personal and commercial use with no attribution required, (though we love it when you link to us). We take great care to only make illustrations available that are either out of copyright, have no copyright protection, or have been dedicated to the public domain.
The creator died in 1943, so this illustration is in the public domain where the copyright term is the creators life plus at least 80 years.
It is important to state though, that copyright protection periods differ from country to country. It is your responsibility to ensure that the image is suitable for use in your country.
