I've uploaded another variant that seems to have Bridgeport fonts as well, but the Roman numerals in "Part I" and "Part II" have no serifs, unlike the earlier 1941 Bridgeport version.
Full-page Columbia ad for Harry James in Billboard of June 14, 1941, as linked by xiphophilos, also uploaded as image here. The same Billboard issue also contains a review (by Daniel Richman) which I have also uploaded (print not easy to decipher though).
Thank you for the update! I'll change the date in my spreadsheet to 1944. I joined this community in late December last year and am always amazed at what I learn from all of you! Thank you!
Both of these pressings are Bridgeport, CT pressings. MikePasta's labels are from ca. 1944, mine are earlier.
In response to a PM from me about these label sets, W.B.lbl. explains:
"{Images #1859924 & 1859925} might've been from a circa 1944 pressing. During '44 especially, many pressings were shorn of the Bridgeport fonts seen on {Images #1689041 & 1689044}. And don't forget, many singles remained on active catalogues for years. This factor explains later pressings with other text below the label name in other examples. Also, during the war, the gold print changed from the gold leaf to something more relatively silverish.
Later '43 would have been {Images #2737271 & 2737272}; not only was there the matter of the Bridgeport typesetting switching from serif to sans serif type for the songwriting (and part designations), artist credit and personnel, but the add-on of an extra ~1.14" pressing ring."
