Here's my Atlas contribution. I'm enjoying the history lesson Thunder!
Standard had a very visible presence here on the Central Coast of California. Every small town and niche on the Coast Highway had a Standard, or later Chevron, station at one time or another. In most cases they were the first brand to pop up with an exclusive on a station. The other early stations were pumping multiple brands.
Tell me when you're ready Thunder and I will post some station pictures.
