An outstanding post-war American artist book, featuring collaborations between four of the most influential American poets of the second half of the twentieth century, and four important second generation New York School artists. 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 an awareness of some real relationship between their work" (prospectus).
