Abraham Lincoln statues

[David Lockmiller]

"The only personal request [Vinnie Ream] made of [President Lincoln] was that he sign a copy she had made of the Emancipation Proclamation. He signed it and had Secretary of State William Seward sign as well."

Vinnie Ream, an American Sculptor by Edward S. Cooper (2004) p. 18.

I tried to find the location of this actual "Lincoln" document with Google but without any success. What would be the monetary value of such a document?

I found the following reference in the Manuscript Division, Library of Congress:

Vinnie Ream and R. L. Hoxie Papers
See bottom, page 6.
BOX OV 2 not filmed Copy of Emancipation Proclamation (signatures of Abraham Lincoln and William H. Seward not in their respective handwriting)

"not in their respective handwriting" may be a mistake by the archivists

Catalog Record: https://lccn.loc.gov/mm79026674

If it is real, it would be nice to have the actual document on display in the Abraham Lincoln Presidential Library and Museum along with materials on Vinnie Ream's Lincoln Bust at Cornell University library and the Lincoln statue in the rotunda of United States Congress.
