With its old-timey feel it really stuck out among the (sterile looking in comparison) printed signs.

Let me caution, however, that this is nearly varsity level signage strategy. The imperfections of this sign are an asset only because it is surrounded by decent looking professionally designed signs. Much like library websites need to be easy to use before they can be filled with social goodness, signs in a library would have to be cohesively well designed before they could benefit from something like this.
