Mark . . . Bill is using 3 different types of pictorial oils . . . yes, the Danacolor - but also Chromatic's and Classic . . .
Perhaps Danacolors only makes those now . . . Bill bought up all the pictorial oils he could long ago figuring he'd never run out . . .
Unfortunately he didn't see this project coming . . .!!
Mike . . . you're welcome. It takes a lot to keep everyone updated - but it seems like a project many could learn from.
In answer to your question, yep, they are only in Illinois - from the Indiana border to the Mississippi River . . . in 40 different towns. Yesterday we put up Joliet's mural (yes, THAT Joliet - as in the Blue Brother's)
Here's Eddie Weiber's new article (with a brief history) that will be in next month's SignBusiness:

We cross (and even run congruent with) Rte. 66 near Plainfield, IL - and intersect with the Dixie Highway in Chicago Heights, IL . . . this state got its Federal Scenic Byways status in the last 10 years (1/2 the source of this grant) - and those intersections were part of the lynchpin of that approval. We're truly here in the 'middle' of the country - first place south of the Great Lakes to go due west . . . so it isn't a surprise that other roads came through this state.
The LH ran from 42nd Street in NYC - all the way to San Francisco . . . and they say it was 'paved with ink' since it was mostly 'hype' and the reality of the 'road' really being just connected dirt paths in the more rural areas.
I just know I'm destined to be a Lincoln Highway Historian geek when this is all done . . . speaking to lunch groups of the DAR, etc. when I'm ancient and my earlobes start hanging to my shoulders . . .

I am learning how transportation truly made this country grow . . . maybe the single greatest source of that growth since it connected communities and small businesses . . .
It's an honor to work on it . . . and I still feel like I'm riding Bill's coattails. He's making my designs look even better with such amazing quality in his pictorials. Poor me . . .
