apograph
A copy or transcript of a manuscript (called the antigraph).
Moreover, this is not a holograph but an apograph, made by a scribe for the printers – you will note that both mayors write the same hand.
Where it comes from
Borrowed from Ancient Greek ἀπόγραφον (apógraphon), from ἀπογράφω (apográphō, “I copy”), from ἀπό (apó, “off, away from”) + γράφω (gráphō, “write”).
