I would agree that -- as others described -- the full set is not for the faint of heart.
I'd also mention that technical grades mean almost nothing for this set. There are plenty of great looking 1's out there, and they frequently look just as nice as the 3's, if not nicer.
I've been lucky to make it to needing only one card for the set... That pesky NY Demmitt is what I need, so if anybody has a lead on one...
Good luck if you choose to pursue the set or any side projects within it!
Cheers,
Steve
