From the Lawrence Daily Journal-World for Dec. 27, 1911:

“Did you ever walk north on the south side of Tennessee street where it intersects with Berkeley [currently 10th] street, after night when the electric light is turned on? Ever notice a peculiar shadow cast on the sidewalk just as you pass the intersecting one to the east? You probably did not unless some one pointed it out to you, but nevertheless there is one of the most peculiar phenomena that one could imagine existing on this corner. In the very heart of the residence section of Lawrence and yet it is known to exist by but a very few people, although it has been there ever since an arc light was placed at this corner. Look carefully at the base of the big elm tree that stands on the southwest corner and you will notice some peculiarly shaped roots that are uncovered with earth, the latter having been taken away when the sidewalk was put in. If you followed the shadow cast by the light in the street from these roots you will immediately be struck with the likeness to a human face cast on the sidewalk…. a perfect likeness to that of the pictures we see today of Abraham Lincoln. The roots about the base of the tree bear no resemblance to the shadow whatever, and it is only by the shadow that they cast that one is attracted to stop and look and marvel. The face is perfect.”
