You could well be right with the "cartagloria" suggestion, the mirror looks like it has a good age and a similar shape to the silver profile. Are you of the opinion this was made in Portugal and is the "shield" a maker mark ? The mark like a divers helmet on its side is one I have not come across before and cannot find it anywhere yet. It seems that this mark and the crown above are from separate punches which is strange.
I think it is not a "cartagloria" but simply a mirror...it resemble it a bit but very different for me... Antique cartagloria are a repoussed silver sheet on a carved wood so the repousse work is deep and no with small details, becuse the silver has to cover the carved wood
correct observation amena, cartagloria has to stand on the feet and I apolgize. My comment "cartagloria are a repoussed silver sheet on a carved wood so the repousse work is deep and no with small details, becuse the silver has to cover the carved wood" is not correct; I was lead in error by the two type of cartagloria, the ones in wood only and the ones in silver sheet.
I did think maybe Portugal or Paris but another possibility might of course be Hanau. Any thoughts on this or has any member come across this set of marks before that point towards a definite country attribution.
