This one was truly the most unique 'thank-you gift' I've framed.  The gift giver had this old vellum, red-wax sealed document of a sale of property framed for her friend - who is also into property.  When I say old, this document is dated 1620, and written in Latin.  Very Cool!  A lot of thought was behind this gift - I'm sure they were blown away by this!  Due to 'most' of us not knowing Latin, and very old Latin, at that, an engraved brass plate was added to give the details of the document.
