Comment by W.B.lbl:
I'd've left it at January 1956 in terms of its release and no exact day, especially given Billboard's "Review Spotlight" date.
The label fonts on both copies shown are from Progressive Label & Litho Co. of Brooklyn, NY.
Comment by xiphophilos:
Is there any evidence that this record appeared as early as December 1955? On
Wikipedia, I find that it came out on January 10, 1956, but also without source reference.
