I just saw that the American Highway Road Atlas has come out with a 2020 edition (complete with a new cover photo). While I buy Rand McNally every year, American Highway is also one of my favorites. According to the cover, they've increased the number of City Maps from 336 to 355. I'll need to place an order for a copy. The only place I've found it available is online from Mapping Specialists.
From a glance at the sample images it seems to use the same cartography as the Michelin North America atlas. Or does Michelin use the American Highway cartography :hmmm:
I think the cartographer is Globe Turner, whoever that is. Both atlases use the same cartographer, they just design their atlases differently.
