When she was little, Vianna Zimbel loved playing dress-up with her grandmother’s old costumes. Grandma was Boston opera singer Beatrice Wheeler, who sang Aida wearing this headdress and belt on some of Europe’s most famous stages. Zimbel has the 1912 program photo of Granny wearing the jeweled ornaments to prove it. When she got the appraisal, Zimbel was ready to break into song herself. She says the ornate “bling” will be enjoyed all the more on a future Halloween.
