A decorative plinth taken from the White House during renovations in 1902 will lead RR Auctions' Remarkable Rarities sale on September 24.
The elaborately decorated plinth was built in 1817 to repair damage sustained in an attack by the British in 1814.
It displays 17 layers of paint, applied over the course of its long history, and was removed under Roosevelt in 1902.
RR comments: "Despite the apparent availability of such pieces in 1902, they have largely been lost to history; the few fragments of the original White House that are known were used to make some sort of souvenir, such as a small box or gavel.
"This is, as far as we can discern, the only White House piece that retains its original paint.
"Seated in the primary hallway on the first floor of the White House, this plinth is a true witness to history that represents the lives���public and private���of the presidents from Madison to Roosevelt."
Egyptologist Howard Carter's handwritten measurement of Tutankhamun's tomb is likely to prove another highlight.
The lot provides a fascinating link to one of the most sensational archaeological discoveries of all time.
No estimates are available for either lot, but we will keep you updated.
