Drool.
I love the 1390131, it is my favorite, and I have always wanted an old-school label. I thought that they were only seen on 1390120s.
If blue-label 1990s Ms are selling for $60-80, this one should be worth well over $100.
If I was more flush right now, I would gladly go $120-130 shipped, but alas.
Rarely do I get excited over Model Ms anymore, but this one is really special.
