Hard to find copy of the Mobile Post Office Society U.S. Highway HPO Cover Catalog and Register issued in 1987. Unbound, with no holes punched. My research indicates this catalog was issued this way.  Overall good shape, no rips or missing pages a few curled pages edges. Catalog/Register is complete with all 67 pages, as issued. Check out the photos.

Order will ship within 24 hours of purchase (m-f).
