Congratulations! Filling that last hole will definitely be satisfying.
I've been slacking a little on my Jefferson album and have used some purchases for hole-filling and upgrades. I have some sets on the way that will allow me to add a couple proofs as well. It may sound like cheating but, hey, it is a 1938-2003 set w/ proofs!
