The inscription on the plaque includes this quote:
“If they are to put up any memorial to me, I should like it to be placed in the center of that green plot in front of the Archives Building. I should like it to consist of a block about the size [of this desk].”
I don’t know if it’s hubris to expect a memorial and to request a specific type, or if it’s a sign of humbleness to be aware of the possibility of a memorial and not wanting something ostentatious.
Located at 9th Street & Pennsylvania Avenue, northwest of the National Archives.
