We'll admit: this is not our finest example of a ghost sign.
But, we believe there IS something in this photograph.
Looking up Race, from the northeast corner of Washington Park.
See it yet?
Okay, it looks like simple discoloration, we admit.
(We used a real digital camera with a real lens on this.)
And oddly enough, the phone camera seems to bring it out.
And in person, it's as clear as a bell. Provided the light is good.
