Interlochen, Michigan has a national music camp where young musicians study symphonic music for eight weeks each summer. These photos by Arthur Siegel are from 1942; Interlochen Center for the Arts is still going strong today. Unfortunately this set only shows the campers engaged in various recreational activities; the ones of them actually playing music are too lo-res.
