The success of the Daily Oklahoman and Oklahoma Times, along with OPUBCO's agricultural monthly magazine, the Oklahoma Farmer-Stockman, established in 1911, soon enabled the company to invest in real estate, oil and gas, and other ventures. When the Great Depression of the 1930s occurred, many passenger trains ceased to run in Oklahoma. Consequently, OPUBCO started Mistletoe Express, a truck line, to deliver the newspaper statewide. The firm soon grew into a major service for other Oklahoma businesses. By 1971 Mistletoe Express had terminals in more than fifty Oklahoma cities as well as in cities in four neighboring states.

I am looking for any old pictures of the building with the old sign hanging out front and also pictures of there old delivery trucks.
Any help would be appreciated.
