From some other website I just now found...
“On Sunday, January 26 [2014] Leigh Keno will hold a single-lot sale at his gallery at 127 East 69th Street. At 1 p.m., he will sell a newly discovered document written by Robert Livingston. It is the manuscript for the 12 colonies’ last attempt at reconciliation through redress with Britain, written a year before Livingston was appointed as one of five members of the committee formed to draft the Declaration of Independence. It was known only in printed versions that were circulated in the colonies, and it was not known that Robert Livingston wrote it until this manuscript was discovered by Emilie Gruchow, archivist at the Morris-Jumel Mansion.
She found the eight-page “letter” in a folder with various 18th-century doctors’ bills. Handwriting experts have verified that it is indeed in the hand of Robert Livingston. It is a first draft, heavily edited, of what was published as “Letter of the Twelve United Colonies to the inhabitants of Great Britain.”
There were only 12 colonies in 1775 because Delaware was still part of Pennsylvania.
Keno estimates it at $100,000 to $400,000.”

Don't think so. PA and DE legislators met separately starting in 1704, although the Penn family still appointed the same governor for both their possessions.
I don't know why this document references 12 colonies, if it does, but I doubt it has anything to with Delaware being part of Pennsylvania in 1775.
