By the way, if you want to try this image in WhatTheFont for yourself, click on this link and make sure to change the "c" to a "c" (the initial letterform pass mistakes it for an "e").

Then it will show you all the matches. You'll see how they're all CLOSE, but not exact. WhatTheFont essentially comes to the same conclusion that our graphic artist and I came to: it's not a common standard font that can be found in your average library.
