May be cheating to have two... but just one is so hard

Otherwise I would probably have chosen a painting. This version (There's 3 of 4 takes on this by different Flemish painters) of the
Money changer and his wife by Marinus van Reymerswaele is one I have very fond of.

The woman is incredibly beautiful, lifelike and detailed, especially. Had the chance to see it up close too.
