Frog Concert Crystal Dome Button 1.25" by Susan Clarke # SC-1111
Slightly domed clear acrylic top, over an antique reproduction photo. 1-1/4" diameter, small shank opening on the antique brass finish. From Susan Clarke, made in her studio in the USA.
Remove before cleaning, or cover with aluminum foil before dry cleaning. Washing with water may eventually dull the finish, but a good car cleaner can restore the finish if that happens.
