Frederick Paige began producing cars in Detroit in 1909. A few years later his successful Paige-Detroit firm erected a large brick factory on 21st street, presumably within walking distance of 21st and Vernor Highway. Am I correct in think that none of this plant remains? Almost all of 21st street has been removed.

A large former Graham-Paige plant stands on West Warren near the intersection with Lonyo, a plant that was used by Chrysler for several decades. Was that plant built by Paige-Detroit or was it built after the Graham brothers purchased Paige-Detroit?
Was that Graham-Paige plant designed by Albert Kahn? It has what looks to be a Parducci carving on the front of the office building that faces West Warren.
