Plaza Music Company was the distributor of Banner and other 1920s popular dime-store labels (Domino, Jewel, Oriole and Regal). Their assets ended up with ARC (American Record Company) in 1929 but the company itself continued with the Crown label after 1930. Plaza announced their own portable, the PAL phonograph, in June of 1922 and followed up with the Kompact cameraphone likely after the original cameraphones came to the US from England in 1924. I am under the impression that Plaza made the phonographs in the US using parts from Thorens, who had an office in NY. However, I'm not fully convinced as Plaza could just as well have bought whole branded machines from England, whose gramophone industry was heavily dependent on Thorens parts.
