Notes:
Charles W. Arny (born 1831 in DC) was listed in an 1858 directory as a bottler of porter, ale, and mineral waters, living on Washinton street near Bridge Street¹.
Riley Shinn owned the Union Hotel in the 1860s. He also owned a bottling establishment that turned out stout, ale & porter³. Shinn is listed in city directories at "57 Greene" or "Greene cor Olive" between 1863 and 1871. In 1872, "Palmer & Green" is listed at the "57 Greene" address. Greene street is currently called "29th Street NW".
Three of the five "Arny & Shinn" bottles listed in the book⁴ are pontiled, so these are old bottles. The book⁴ also lists a pontiled bottle from "Maack & Arny".
