March 1928 - Petroleum World magazine
The oil industry was particularly enamored by the Gotfredson design. A March 1928 issue of the Los Angeles based Petroleum World magazine ran an advertisement for Gotfredson model trucks between one and ten tons, with special equipment available to suit oil field requirements. The advertisement included a picture of this Gotfredson truck bearing the logo of the Pennzoil Oil company branch based in Bakersfield, California -- 100 miles northeast of Los Angeles.
