Spring Cleaning: 1950s "Juniors" Quartet 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 wood frame with satin-y glass. Pictured are two cool old National amps, a standard National catalog-style lap steel, older Lange-made (?) tenor banjo, 1930s Gibson L-00 flattop guitar, and a mid-50s National electric archtop (with adjustable neck). Also: way cool shirts! Cowboy fever.
