Every once and a while I'll stumble across something that is too unique to pass up. And this 1896 bicycle map of California roads definitely qualifies. Complete with the original advertisements, this is close to a must have for you touring nerds out there (myself included).
Pending your desire for this type of historical artifact, I found some reproductions on Zazzle. Though not sure that I would rely on such a map for directions now a days. Then again, I don't need a map, I always know where I'm going (at least according to the super sexy British voice on my TomTom).
