I posted this over in the NJ thread, but it’s much more appropriate here.
This pic was taken at Airport Circle in Pennsauken. The incorrect sign is the street name blade. On Armistice Day (Nov 11) in 1929, the boulevard to the Ben Franklin Bridge was renamed from Bridge Boulevard to Admiral Wilson Boulevard to commemorate a Camden native and WWI naval hero.
Except that they forgot to make it official. Fine, in 1937, they finally codified the name change with an official ordinance.
This sign was installed LONG after either of these events, so not entirely sure what the heck happened here.
