Based in the Washington D.C. area, Brian Cassidy Bookseller @ TPM is the counterculture department of Type Punch Matrix. We deal broadly in 20th century popular culture and avant garde print materials: books, posters, manuscripts, ephemera, and the like. Specialties include artists' books, literature and poetry, little magazine and the mimeo revolution, punk, outsider and vernacular books, photography, and archival materials. We actively buy books, from single titles to entire libraries.
