LTTR is an independently published art journal/zine by the LTTR collective.
LTTR seeks contributions from artists in feminist and genderqueer communities. Each issue uses the title LTTR as an acronym for its subject. Each issue has existed in different shapes, sizes and formats and has allowed artists to include unique editioned posters, objects, and individual artworks with the journal. The collective artists have included K8 Hardy, Ulrike Müller, Emily Roysdon, and Ginger Brooks Takahashi. Contributors have included Alvin Baltrop, Edie Fake, Kate Huh, G.B. Jones, Zoe Leonard, Gloria Maximo, Eileen Myles, JD Sampson, and many others.
LTTR was one of the independent publications included on the Mobilivre-Bookmobile traveling library in a 1950s Airstream trailer tour of North America.
