On display at the Putnam Museum and IMAX Theater in Davenport,
Iowa is this gold-plated Bach Stradivarius Cornet (serial no. 0620;
bell-mandril #106), purchased in February of 1927 by Leon Bix
Beiderbecke; whose middle name is engraved on its bell.
Update: The webmaster of a Bix Beiderbecke tribute site, under the impression that the above image was knowingly extracted from his corner of the internet, has insisted that we here at If Charlie Parker Was a Gunslinger . . . alone among all other sites and blogs who've posted it, provide a link to its presence at his site as well. We are, as always, happy to comply with even the most polite request.
