Pete Seeger and that Mid-Century Look

That unique mid-century look jumped out at me as I enjoyed the coverage of the life and career of Pete Seeger. A sociological aside: In the nascent years of the folk boom the singers often wore suits and formal attire! At a certain point, Pete never wore another tie in his life. He shed that look with a vengeance, dusting off his work shirts and adding rainbow colored knit caps as the 60s blossomed. I guess being blacklisted will strip you of mainstream aspirations.
