The Metropolitan Museum of Art has nearly 400,000 images online, almost all now in ‘just about’ print-res, and…

“that the Museum believes to be in the public domain and free of other known restrictions; these images are now available for scholarly use in any media.”


Above: “A Fury Riding on a Monster”, by Cornelis Saftleven, mid 17th century.

A sample download gave me a 72dpi picture at 3000px on the longest side, which (with a bit of Photoshop work) would just about hold up at A4 size and be able to fill a full page of a print magazine.
