Jonathan Safran Foer has long had a passion for the work of the twentieth-century American assemblage artist Joseph Cornell. Inspired by Cornell's avian-themed boxes, and suspecting that they would be similarly inspiring to others, Foer began to write letters. The responses he received from luminaries of American writing were nothing short of astounding. Twenty writers generously contributed pieces of prose and poetry that are as eclectic as they are imaginative, and the result is a unique collaborative project and one of the most significant engagements of literature with art for many years.
