In December 2010, the family of Johnny Cash auctioned a collection of the Man In Black’s personal items, including handwritten lyrics, poems, the blue jumpsuit he wore during his legendary performance at San Quentin prison ($3000 – $5000) and his vintage 1951 Martin guitar ( $20,000 – $30,000).

Also, the above to-do list.

Without doubt, the coolest to-do list in existence.
