This is such a great image of a knight on horseback with a beautiful white horse and a knight in armor. This copyright free public domain image of a knight and his steed would make a great image for your next creative project.
Randolph Caldecott (1846-1886) illustrated the 1892 book Old Christmas where I found this vintage image.
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.
