Lyre back chair at Antiques on Jackson HERE
I love this set of metal chairs. Kind of a cross between an old ice cream parlor style chair, and an elegant ballroom chair. They would be great dining room chairs, or great in the garden. You could have them sand blasted, and made to look sleek. You could just sand off any crusty bits that are ready to fall off, and put a low sheen sealer on, leaving the beautiful rusty patina revealed in all its glory.
