I like old road maps, and I’m apparently not alone. Ian Byrne’s Petrol Maps is one of several web sites dedicated to collecting and documenting old road maps; this one looks at maps of Europe issued by oil companies. Via Things Magazine. But I’m surprised, though, that this site, like others I’ve linked to before — see previous entries: Early Highway Maps, More Road Maps, Art of the Road — doesn’t actually show the maps, just the covers. I wonder why that is. (Having said that, there’s a lot of material about the history of these maps that is just invaluable.)
