I am trying to find an image of the back of Euthymides' Reveler's Vase where he inscribed "Euphronius never did anything this good." There are tons on images with the scene of the revelers, and I have searched everywhere with every possible search phrase for an image of the inscription to no avail.
The inscription is on the front, just in very small letters. Really you'd need to look at it in person to see them clearly. Here's a large image where you may just be able to make out some of the letters between the figures. And here's a book that talks about the inscription.
