What happened to the Declaration if Independence?

On this, the 239th anniversary of the announcement of the creation of the United States of America, I got to wondering.

What happened to the one sent to George III? Unlike the “engrossed” copy we are all familiar with* it was signed only by Hancock as the President of the 2nd Continental Congress and Thompson as Secretary.

Was it torn up into little bits? Is it in residing the the UK archives somewhere? Is it hanging in Elizabeth II’s drawing room as a reminder that sometimes what seems bad works out in the end?

*That wasn’t written up until July 19th. Most of the signing was done in August and into September as various members of CC2 could make it to Philadelphia.

To save some clicking and reading…

What kind of ink would be used in 1776 on a document intended for History?

Why would it fade so badly so quickly? Even with the 1820 “wet process” transfer (which lifted some of the ink), wouldn’t even plain old india ink be more stable?
