Whoever enters the so-called "publication data" for 78 rpms on archive.org is, as a rule, not very critical.
They often get their dates from http://www.78discography.com/, as in this case, without realizing that that database only offers recording dates, not "publication dates". Or they get dates from discogs, which can be a really mixed bag, or from here, which is frequently the most reliable source because many informed users are vetting these dates.
Nevertheless, even here you'll run into unsourced or simply erroneous dates, not least because you aren't the first user who has entered recording dates as release dates, and we don't always catch this right away.
Your most reliable, but far from complete source for the release dates at least of U.S. American releases is the Database of American Historical Recordings. It's not complete, though, and when their dates are based on the listings in The Talking Machine World, they are usually a month later than the actual release date. When TMW, for instance, lists a record under "Advance Record Bulletins for January 1920", you can assume that the record appeared in late December 1919, which is when contemporary newspapers advertise these records as "For Sale Now".
Entered date (17 Jun 1926) is the recording date, see also Country Music Records: A Discography, 1921-1942 by Tony Russell and Bob Pinson, page 258.
What we want here as the "Date" is the release date though, and that was like Mike Gann says: as the record was announced in The Talking Machine World's Advance Record Bulletins for March 1927, it was released in late February 1927.
