This photo was taken by a Bix fan at the “Jazzens Museum” in Sweden. But after that fan posted the photo and began an engaging and lengthy online forum discussion–as seen in the link–about this particular cornet, the consensus is that it is more than likely not a cornet that Bix owned and played.
I guess that’s what happens when one just randomly grabs photos from the internet and uses them before researching the origin or authenticity. Lesson learned. It’s too late to remake the video now so enjoy .38 seconds of Bix’s solo which may or may not have been played on the above pictured cornet.
