Pictured here is a copy of the original Statement of Principles as typewritten by John Hospers at the 1972 convention. The existence of this original document was unknown until it turned up on an ebay listing, was purchased by a Libertarian Party member, and then donated to the Party. The seller said that her parents were early activists in the California LP and as she was disposing of their estate she found this document hidden behind a framed, photocopy picture of Ayn Rand, where it has likely been for decades.
This special document has since been framed and will be on display at the 2018 Libertarian National Convention; after that, it will be sent to LP Headquarters, for its permanent display and safekeeping.
