Typically, 800 series streetcars were assigned to the Desire line, but once in a while, a low-numbered 900 might appear on the route, as here.  These undated photos were probably taken on the same day by the same unknown photographer, some time between 1945 and 1948.  The upper photo shows car 904 heading toward Canal Street on Royal at St. Peter Street.  The lower picture features the same car on Bourbon Street, leaving Canal Street, which can be seen in the background.
