Chicago 6.50

Thinking to name a business? Do us Chicago proofeaders a favor; exclude the comma from your company name. Can someone inform Latent Print where the , Inc. trend got a foothold?
Forego Inc with the extra character, I think not. Yet, Chicago instructs, if the comma must appear, place the mark fore and aft.
To make a thorough job of it, better get on the phone with the business's press agent for official guidance. One can't Chicago the whole world.

Here's a blog about erroneous business signage.
And here's Lynne Truss's best-selling book supporting proper punctuation as a cause. (Worth trumping deadline, really?) My aunt (quoted here), a British Literature specialist and English teacher at this Delaware high school, recommends the book, another for my library queue.
