For what it's worth, on newspapers.com the Kostelanetz/Gershwin album MM-559 starts showing up in reviews and advertisements beginning in April 1945.

For display purposes, I need to know the approximate release date of Music
of George Gershwin by Andre Kostelanetz, Columbia album set # MM-559,
including discs 4310-M through 4313-M.

 

I don't recognize enough of the stuff advertized in the back cover.  No war
bond ads, but a list of OPS Ceiling prices, nice picture of laminated
process

 

Mostly need to know if this could have been found in a record store in 1945.
