Greetings, anyone know of a source to reproduce 15-20 of the attached 20" diameter, 1-sided metal sign pic ? it is fairly heavy,silver brushed metal patina, ? Also, if there is a durable product out there to substitute in place of metal. they like this sign they had done a while back ,and want to keep it consitent-but within financial "reach"-that's always the down side huh ?
