Is this the Lincoln Highway's oldest graffiti?

The Icon keeps an eye out for Ada area oddities. This one is certainly in our top 10.

You'll find this cement fence post on the corner of Phillips Road and Lincoln Highway. The top of the post reads: "Sept. 1 1912." It was written in the post before the cement hardened. There's even an artistic design above the date.

The person who wrote the date on the post is unknown.

To make it more interesting, this could be the oldest existing graffiti - we are stretching the definition here - related to the entire Lincoln Highway. The highway was conceived in 1912.
