The Pow-Wow Club was a Philadelphia literary club founded by Dr. Rosenbach and several of his friends in 1893. The donated materials belonged to the donors’ grandfather, who was also a member, and include program booklets for the club’s anniversary dinners and ladies’ nights, as well as the club’s minute book for 1908-1914, which contains laid-in material, including letters, by-laws, membership cards, and a membership contact list.
