No one is immune from bloopers. Especially not anyone who deals in written information. Typographical errors are a fact of life in the printing industry, and many of them were made by the contractors stamping their names and street names into the concrete. We get a great delight out of these typos, perhaps because they give us excuse for our own mistakes.

As we showed them to other people they wondered how they happened. Were the workers illiterate? Hurried? Inattentive? Mischievous? One case, at 30th & Division, is so egregious I believe it must have been deliberate. Maybe the concrete finisher got laid off that day and did it to anger his boss.

We hope you will go out and see them for yourself and come up with your own answer. Let us hear from you, with your comments and reactions. And, of course, if you find any more, please let us know.
