While I am still unable to locate anything at all from the ur-Shorin company known as American Leaf Tobacco Company, new (to me) items from their successor company American Gas Stations keep popping up. Today it's a thoroughly magnificent circular touring "wheel" chart:
It's fairly large, measuring 10 1/2 inches in diameter and fully functional, although I doubt very few of the routes given are viable anymore. With only four AGS locations shown, I can date this item to circa 1934, which is when the Shorin family had at least four corner service stations in operation; they would end up with about fifteen of them before Socony (now Mobil) scooped them all up as they blotted out smaller competitors in New York throughout the 30's and early 40's.
Here's some better detail, although the size of this sucker makes it a little difficult to get everything in the shot (the above is from the eBay auction):
One of those two California trunk lines would still be recognizable to modern travelers, although you would be hard pressed to use it now for its original purpose. I'm referring to Route 66, which still begins in Chicago and ends in Los Angeles, or vice-versa. The second would be the older Lincoln Highway, which actually ran from New York City to San Francisco but was more of a series of interconnected roads (and occasional almost-roads) rather than a planned highway like 66 was.
The back had a reasonably organized list of the various destinations you could reach:
I'm not sure how these wheels would have been distributed but they certainly could have been a premium-style "loyalty" product given to the more free-spending customers of the day or even retailed along with other maps, such as they were, at the time. No matter, it's a fabulous piece of a fast-receding American past.
