This plain, almost forlornly so, hat was produced by Beistle during the 1950s. By this time, Beistle's artistic creativity was nearing a bottom. (Compare this design to any of their designs produced during the 1920s and 1930s and you'll immediately see what I mean.) There isn't much demand for this hat. The seller has it starting right at SGV.
10/31 Update: It sold with one bid at $24.99.
