New Orleans Public Service Inc. (NOPSI) continued use of tickets of this type for company officials.  The main difference between these two tickets is the facsimile signature of the current president at the time they were issued, the upper ticket (series J) being the older.  (The series U ticket, and several following, show mildew caused by surviving the floods that followed Hurricane Katrina.) — Collections of Louis Hennick (series J) and Earl Hampton (series U)
