The fields are pretty dark in the photo, so it's kind of hard to see if there are any hairlines. I would guess (just for the sake of guessing!) Pr-68 Cameo. There looks like a vertical mark in the frost on Jefferson's forehead. Do we get more than one guess? My second guess is Pr-67 cam.
If those aren't right, let me know and I'll be happy to guess again!
