A routine search of the Library of Congress called up this tantalizing gem: an old cage elevator etching labeled “D.C. Wash. White House. North portico. Bordered with 8 state seals and busts of10 presidents” and “This record contains unverified, old data from caption card.” and “c1907”. The caption is obviously wrong, but if it really is something to do with the White House, then it’s surely the original elevator or second elevator (I think there have been four).
Then there’s this interesting pic of JFK in what is clearly a White House elevator, but which floor? There is a dead end where the staircase should be, which is a little baffling. Since he’s with Caroline (or is that Eleanor Roosevelt?) he could be going to her classroom on the third floor. The golf clubs suggest a part of the family quarters, maybe the sub-basement.
