Co A-2297 (ODJB) - added the original label type (FZ) and very late types (EW, GW). FZ-AW labels have credit ORIGINAL DIXIELAND JASS BAND, but on EW-GW (1920 !) this is changed to ...JAZZ... . There are many label variations between FZ and GW, including a different layout of the credit and the spelling ...Strutter's... .
FZ is the first printing date code used by Columbia, confirmed for A-2293-2298 and apparently first used in the 10 Aug 1917 Mid-Month list. Co A-2289 is known without date code, and A-2290-2292 are only known with later date codes. A-2307 is the last known FZ.
I've updated the "Christmas Morning At Clancy's" record (Columbia A2402). It was a mid-month list release as well, see The Evening Star, Tuesday, December 11, 1917, page 14: Columbia Mid-Month Records - Just Released.
Thanks, xiphophilos, for finding this. It may help me to convince other moderators that a record like "Christmas Morning at Clancy's" (Columbia A2402) was not released in January, after the event, just because it was listed in the RECORD BULLETINS FOR JANUARY, 1918 in Talking Machine World: https://archive.org/details/talkingmachinewo13bill/page/124/mode/2up
Same e.g. for "Am Sylvesterabend (New Year's Eve)", Columbia 47350, from the same page.
This record formed one of the first eight releases (Columbia A2293-A2298) in Columbia's first ever "Mid-Month List" (released August 10, 1917), when Columbia added a second release date on the 10th of each month to the customary release date on the 20th of each month:
Columbia announced this first Mid-Month List with a double-page ad in The Talking Machine World, July 15, 1917, page 16-17 as follows:
"On August 10, we will place on sale eight records - each a big special, each a big SELLER.
We shall advertise these records extensively, send you a special hanger, and include them in the coming September supplement so that they will sell all over again when the September record list comes out."
