Framing Goddess
SGF, Supreme Grumble Framer

NYC vintage Vignelli subway map, this is thickly laminated as it was used in the cars. The laminated map is sturdy, rigid and a matte finish. It is heavy-ish, it can't be rolled, to give you all an idea of it. The goal is to "float" mount this (edges exposed) in a c/p fashion with spacers under the glass. Yes, it has value. I discussed mylar corners with this customer and he was fine with them. It seems , however, that because of the weight of this, it may want to "belly" out of the corners. I could add a mylar belt on that belly (teehee.) I don't want to adhere this in any way, I'd really like to use a mechanical mounting method. I considered formed brass rods, but I can imagine them "denting" the edges.
If we must, I will tell this customer that we need to overmat it for the needed support, but I'd like to exhaust all other floating options.
And I suppose we could slap the glass right on it, too.
Anyone?
