Pure Oil — Petroliana History, Marks & Collectibles

The story

The Pure Oil Company took its modern form in 1914 and became one of the most design-conscious brands on the American road. Its signature was architectural: the "English cottage" service station, with a steep-pitched blue tile roof and white walls, designed to look reassuring and domestic rather than industrial.

That blue-and-white identity carried straight into its signage. The tidy "Pure" script and the arrowhead-style marks are among the crispest graphics of the mid-century, and they photograph and display beautifully — part of why Pure has such a devoted following despite the brand disappearing in the mid-1960s.

Pure was absorbed by Union Oil (Unocal) in 1965, which ended the marque and turned its blue-and-white signage into sought-after nostalgia almost overnight.

The mark: blue-and-white "Pure"

Pure’s clean blue-and-white palette and tidy lettering are the essence of restrained mid-century design. Because the brand ended in 1965, every genuine Pure piece is by definition vintage — no modern-era confusion.
