This copper crumb tray has a very classic organic motif characteristic of the Arts and Crafts period. It is not marked and is in good condition structurally. I have not attempted to clean this other than wipe off the dust. I really know nothing about the care and restoration of metal so I'm best leaving it alone. One very minor dent in the very edge which could be straightened easily enough. Otherwise it is as shown. It is 8x10 inches.
