What I really like is how this theme is brought into the oil fields.
Got Union '76 Unocal with their orange and blue pumpjacks, and old "oil camps" which are bio-hazards. Texaco with solid Green, or white and black, and things like the classic "The Texas Company" lease signs. Also Texaco had the star and "T" brickwork in their buildings, roof vents with a Star hole stamped out in the tail. Even the mailbox had a metal plate with a hole for the star, and a solid metal "T".
It just shows me how much pride was put into the oil patch back in the days.
