Title: Leaves of Grass [The Original 1855 Edition]
Author: Walt Whitman
Year: 1855
This slim volume of poetry, to which Whitman added until his death (resulting in the hefty "Death Bed Edition"), contains the original 12 poems, all untitled, but which would later become Whitman's well-known masterpieces (including "Song of Myself"); by no means an easy read, this collection is still accessible enough to be enjoyed by casual readers and serious scholars alike.
