A first-edition copy of Whitman's major work Leaves of Grass, which he began writing in 1850, finished in 1855 and self-printed (a 795 print-run) while he was working at a printing shop in Brooklyn sold at a record price of $305.000 at Christie's. The auction house had estimated the book, which had belonged to copper heiress Huguette Clark who died in 2011, to sell between $100.00-$150.000. A previous version of the title sold for $230.000 in October.

Whitman incorporates both views of transcendentalism and realism in his work and the record-breaking poetry collection is overtly sexual and was by many of his contemporaries described it as obscene. The high prices are however not due to the books content but rather it's rarity on the market!
