Thanks for editing my torn A side label. I myself finally found the time to remove the ugly blueish tint from the original 1945 labels, so I have replaced them and moved them up.
I had seen that earlier non-specific Columbia ad, but I doubt that it meant a weightier commitment, especially as "It's Only A Paper Moon" didn't rise much in the charts but reached its #10 peak in the same Billboard issue in which it was highlighted in the uploaded ad. I have revamped your "Paper Moon" label anyway.
The Columbia ad in Billboard, Sep. 22, 1945, page 29 shows that "I'm Gonna Love That Guy" was the original A side. Once a "Paper Moon" rose in the charts, the ads switched the track order.
Matrix numbers are mixed up in the Notes, and "It's Only A Paper Moon" with the lower number was also the A-side according to the specific Columbia ad just uploaded by me (there were Columbia listings with a different order though). So we may flip sides - and also the label images after a little cosmetic surgery of xiphophilos' A-side image.
