Vintage Blue and White Reflective Angled Arrow (Highway Exit) Sign

I guess this one once functioned as a highway exit sign, but taken out of that context what I like is the diagonal of the arrow, making it a good one for actually hanging on the wall to point toward the stairs leading up, or down to the basement, or toward a corner, or at a particular object. Plus in very good shades of blue and white, with some nice craquelure to the surface of the arrow. 

15" x 21" and in good, used vintage condition, with a little light rusting around the perimeter and craquelure to the white as evident. Three holes across center for hanging.
