Spring Cleaning: 1940s WWII Jazz Band Photo

I'm swapping around ephemera in the shop and so some of my collection is for sale (and framed, too).

This one is an original 8x10 in a vintage wooden frame. Presumably these guys are a WWII-era little jazz (?) band picking out tunes on base. I love the simple drum kit and 40s Harmony Monterey archtop (would've been brand new). The expressions are also killer... as are the drummer's tie and glasses!
