Signs of the times

I noticed two signs in Birmingham as I was walking to the station tonight which amused me for different reasons. The first was a large advert for Ozzy Osborne's autobiography. The title of the book is "I am Ozzy". The sign was a large picture of Ozzy with the text, reproduced exactly below, punctuated as shown.

I am Ozzy. This is his story. Read it now.

This seems to be a rather schizophrenic phrasing with the "I" in the first sentence and the "his" in the second. Had the first sentence been enclosed in quotes to make it a title, I'd have accepted it, but as it is the sense is very confused.

The second sign was a small poster in the newsagents, near the chocolate shelf. It was an advert for Terry's chocolate orange. The only problem was that the apostrophe in "Terry's" had been replaced with one of those squares that display on your computer when the font you are using doesn't include that symbol. Most likely, what has happened is that the designer has used an unusual font and when the advert has gone to its computerised print that font wasn't available and it's substituted the square. What baffles me is how it ever went to print that way. Did nobody at all notice this odd character appearing? Did they notice and not care? Did they notice and care but think, "Oh bugger, nobody will notice"?
