"According to:
"An Annoted Inventory of Outdor Sculpture in Washtenaw County" by one Einar Einarsson Kvaran, 1989,
the following claim is made regarding the Old Detroit PO building. In 1932, Emil Lorch then Dean of the U of M School of Architecture purchased, for $200, some remnants from the Detroit PO building to be placed around the architecture building [where they still are, I think] This fragmant used as a base for Carlton Angell's bas-relief as part of a WWI Veteran's Memorial located in Washtenong Memorial Park was likely aquired at the same time. I parrticularly like the use of the word "rebuilt."

Does anyone know if they are still there? I'm specifically looking for that piece that has the shield on it.
