Original oil and gas trade magazine vintage ad for CHESTNUT & SMITH CORPORATION of Tulsa, OK. Cable Address: Naturaline. Their motto: NATURALINE: A SUPER AVIATION MOTOR FUEL. The ad is artist signed but I can only make out the last 5 letters of his name "antee" and is dated 1927. This unique 1927 old petroleum products industry magazine advertisement would look sensational matted and framed. Nice graphics.
