STANDARD OIL CO. OF NEW JERSEY.

The pre-war flag is diagonally divided red and blue with a white S. Brown’s S shape varies slightly, considered a printing issue. Talbot-Booth gives adoption in 1938, but earlier Brown editions already show it; Rosanoski suggests possible readoption after use of Standard Shipping’s flag. Esso derives phonetically from S.O. The purported California ownership does not establish a California flag attribution.
