Proofreader's graffiti

[rhu]

A block from my office (on Athanaeum Street beftween Second and Third, if you're in the Kendall Square area) there's a new building as part of the power plant, and a series of posters on the side of the building. The posters are a sort of modern graphic design lauding the virtues of the electric company.

One of the posters features the word "RELAIBILITY" [sic]

Today I noticed someone had marked it up with the standard copyediting symbol for reversed characters.
