I found the comparisons of the treatment of the Lincoln Bedroom,
here.
I didn't know this before, but it was actually Lincoln's office prior to the addition of the West Wing. The Emancipation Proclamation was signed there, and the original Gettysburg Address is there. FDR was the president who decided to convert the room into a memorial to Lincoln. Good call!
Interestingly (to me, anyhow), Lincoln spent a night in Pittsburgh prior to his first Inaugaration, and the bed was found in the past few years. It had the same style of headboard.
