Notable pieces of equipment to be sold at the two-day event Becker’s 1957 Fender Duo-Sonic guitar which appeared in the liner photos of the band’s 1977 Aja album, a Signature Model #1 Sadowsky, Bacon & Day Senorita S.6 Model, and a 1936 D’Angelico Excel. Some of the guitars and bass guitars are expected to sell between the $3,000 and $15,000 range.

Julien’s Auctions President/CEO Darren Julien said of the upcoming event in a statement, “Walter Becker was legendary for his unique sound, his curiosity, his knowledge, his high audiophile standards and his pleasure in experimenting to find just the right sonic landscape that would best support his creative and musical intentions. This fine and wide-ranging collection reflects all of these characteristics — and more — that helped make Walter Becker one of the most talented and respected all-around musicians and sonic connoisseurs of his generation.”

Becker died in September 2017 at the age of 67. Recently, the City of New York officially renamed a Queens city block after the late guitarist, with a sign for “Walter Becker Way” now posted on the corner of 112th Street and 72nd Drive.
