A contract was part of the $2 million purchase of the only copy of Wu-Tang Clan's . Apparently, there is a heist clause in the contract allowing a member of the Wu-Tang Clan, or Bill Murray, to steal back the collectable album without legal consequences.
The clause reads as follows:
The buying party also agrees that at any time during the stipulated 88 year period, the seller may legally plan and attempt to execute one (1) heist or caper to steal back Once Upon A Time In Shaolin, which, if successful, would return all ownership rights to the seller. Said heist or caper can only be undertaken by currently active members of the Wu-Tang Clan and/or actor Bill Murray, with no legal repercussions.
Clearly, this safeguard was in place just in case someone like Martin Shkreli decided to purchase it. It'll only be a matter of time until Murray plans his caper to return the album to it's creators.
