The collaborators all "lived in New York City where they knew one another well for a number of years and followed one another's work with involved interest. Tiber Press left the choice of partners in this project to the individuals themselves, and, in collaborating, the poet and painter were acknowledging awareness of some real relationship between their work" (prospectus).
