The Investment Building in Washington at 15th and K Streets in 1925, shortly after its completion. Home to the barber shop seen here yesterday, the Investment Building was touted as being the first big office building in the East with an underground parking garage. Ten years ago it was torn down and replaced with a new structure designed by Cesar Pelli, who used the original limestone for the street-facing facades, which were propped up during demolition with a framework of steel girders. Except for the modern superstructure peeking over the top, the new Investment Building looks pretty much like the old one. National Photo Company Collection glass negative. View full size.
