Vox STPL 58.170
This record was a thrift shop find (99¢), a bit worn but still in listenable condition. Sources indicate that the recording was made "around 1954." I was too lazy to photograph the cover this time, which looks just like in the photo above.
From Music magazine: "Novaes plays her 15 waltzes with steely brilliance, non-dogmatic control and a healthy dash of playfulness and thus provides an excellent alternate view of these works."
