The listing, Vintage Stand Alone Mantle or Tabletop Cross has ended.
Beautiful estate find. I believe it is hand cast aluminum, with custom multicolored enameling. It has a beautifully warm patina. Attached firmly to a metal base, it stands sturdily with no wobbling. A beautiful and unique piece. I don't know any more than what I've speculated so far. It measures approximately 8 -10 inches, I will update with a more accurate measurement as soon as possible.
