This black and white dog image is in the public domain. Public domain scotch terrier drawings this cute are not that easy to find so this one might just be the perfect image you need for your next dog-related or scotch terrier project.
I find it almost hard to believe that here we are over 150 years after this illustration was included in a book published by The Illustrated London News, still enjoying it. It was included in the Illustrated London Reading Book, 3rd ed.
This image is copyright free and in the public domain anywhere that extends copyrights 70 years after death or at least 120 years after publication when the original illustrator is unknown.
