Vintage Reversed Carved cameo w/ silver frame * looks exactly like “Whiting + Davis” but I don’t see any hallmarks * cameo is reversed-carved glass / clear intaglio glass * large size! It would be easy to add a chain to this beauty… * pin works as it should * preowned but zero flaws, excellent condition * I accept 95% of offers for the sake of space, so don’t be shy! * smoke free/ pet free home * trade friendly closet
