Well, at least not yet.
A debate Sunday evening among members of the museum's board was to decide whether or not the artifact should be tested to solve a medical mystery that surrounds Lincoln.
John Sotos, cardiologist and medical consultant for the hit show "House," requested that he be allowed to test the pillowcase to confirm that the 16th president had multiple endocrine neoplasia type 2B, a rare disease that would have killed him had John Wilkes-Booth not.
He "suffered from a very rare genetic disorder that affected him, literally, from toe to skull," wrote Sotos in his book "The Physical Lincoln."
The board unanimously denied the request for testing, but left the door open for future testing, if they can figure out a way to safely preserve the strip of pillowcase.
"We do not want to damage it to the point it doesn't exist anymore," Eric Schmincke, president of the board of directors said Monday.
The board plans on contacting other experts to safely extract a few fibers from the strip for Sotos to test.
"We are going to pursue this in the best interest of the museum, of the legacy of Abraham Lincoln and of the integrity of the artifact," board member and Philly historian Andy Waskie told the Philadelphia Inquirer.
