The World Trade Center's concourse was home to one of the most profitable shopping malls in the nation -- and during its last day served as a safe escape route for thousands. The signs being conserved from that area of the trade center include subway signs for the N/R trains and ads promoting the "Death of a Salesman" revival on Broadway. Also interesting but not among these photos: You can still get a small taste of what the concourse level was like. A small but significant portion of the concourse survives at the E train terminus of the WTC PATH station. There, you'll find 1970s vintage metal doors, travertine marble, and subway signs similar to the ones the authority is conserving at the airport.
