Aye parcel shelf hats. Back in the early 80's when the oil yards were at their peak it was the norm for managers with gold hard hats & some supervisors with white hard hats to leave them on "show" in the back window complete with ticker tape title stuck on for all to read & bathe in their greatness....
The managers were supplied with company cars. This was the Yank way, who left a lasting impression on some sad individuals.
I was not a cynic back then, it's only now that I look back & think...oh deary me.
