Seriously, this image is now absolutely public domain:
“Still Life with a Skull and a Writing Quill” by Pieter Claesz (Dutch, Berchem? 1596/97–1660 Haarlem) via The Metropolitan Museum of Art is licensed under CC0 1.0
…Because the Met has decided to put it, and over three hundred and seventy-five thousand other images, into the public domain. You can duplicate them, play with them, modify them, and even use them in commercial work, as long as you use the credit above. Creative Commons already has gleefully put a search engine up.
So if you were looking for classic art for stuff, hey, looks like you’re in luck.

Thank you, Metropolitan Museum of Art. I will suggest that my wife buys more stuff from your catalog, the next time we get sent it.
