Way up there, painted in capital letters, is a mistake that was covered up for decades. The word BARRELS now appears in its original form--either BARRLLS or perhaps BARRLES.

Repainting that turned that first L into an E has been erased by time. Some black "shadowing" is clearly visible. Plus you can still see where extra white paint was "feathered" onto the main shaft of the letter.

The next letter to the right may also have been altered--the evidence isn't conclusive.

The image "This is It!" offers a wider view of this scene.
