If it was my job to slot letters on to marquee signs like this one I’d collect all the letters I need before ascending the ladder, and then check I’d used them all before storing the ladder away. Whatever happened to that ‘N’? Perhaps the member of staff pocketed it and sold it as a ‘Z’ to a rival cinema, pulling the wool over everybody’s eyes in the process.

It makes the absence of the apostrophe seem almost trivial.
