Window Display on rue Quincampoix

I saw this the other day while on a little ad-hoc tour of galleries near the Pompidou Center in Paris. I have no idea what this store was selling, or even if it was a store. Maybe a frame shop? Hard to tell. The frames were in pretty rough condition. But i love the window display, a work of art in itself. For me, the most visually interesting things in Paris are often found outside the galleries...
(if you click on the picture you can see it larger, and notice how dirty the window is - which adds of course to the whole uncontrived "look")
