The first is from the Dixie Roto Magazine, June 19, 1949.

The second is from a Baton Rouge magazine, but I have only the pages of the article and no letterhead.

There are advertisements that have telephone numbers in the old style:
• Spencer Busines College
  New Orleans RA 0112
  Baton Rouge Tel. 8744
• Rotolo's Restaurant, Laplace (no phone)
• Cazenave Motor Co.
  Vacherie St Philip 330-4
