I confess, I haven't looked very much, but if Andy's posting them, I going to assume that I'm right in assuming there aren't too many pairs of dead-stock, c.1945 kid-sized Levi's, complete with the tags, floating around out there.
I'll also confess I don't know the kid's waist size, so it's just as well that I didn't know about them when they were still for sale. Plus, $408, that's like twice as expensive as the typical insane price for children's jeans.
