The Old Manuscripts are a treasure that can be obtained in Sly Cooper: Age of Thieves in the episode Alice in Cooperland. It is worth 244 coins and the time needed for players to reach the safehouse in time is forty-one seconds.
"From Alice in Wonderland to A Christmas Carol, these collections of manuscripts are a huge delight to behold. With so many old and original concepts and ideas left completely in the dark finally coming to light, it's a crime for a thief not to have even a single page."
The treasure is found directly above the Alice statue in the northwest section of the park. Sly's Wizard Costume is required to reach it.
