Polart Records was a label of Poltone Music Corp. (New York), operating during late 1940s. Reissues of Fogg-Record recordings. Earlier issues had only Fogg's numeration, later Polart introduced its own catalog numbers. There are two variants of labels: red on white or (later) silver on red.
Probably not related to Polart Publishing Co. (Detroit, 1960s) or Polart Distribution (Florida, since 1990s till now).
