The November 27 1937 Toronto Globe and Mail contained this photograph, simply labelled “Soprano”:
Edythe Shuttleworth (1907-1983) was born in Moose Jaw, Saskatchewan, two years after the province came into existence. According to the Canadian Encyclopedia, she first performed at Hart House in 1928, made her European debut in Paris in 1929, and sang in New York with the National Opera Company. She sometimes used the stage name Val Yoska, which I guess sounds more exotic.
She retired from singing one year after this photograph, when she got married. None of her performances are available on YouTube, but the National Portrait Gallery has a portrait of her from 1928.
