Personally, if I were producing an item of clothing bearing the name of a famous personality or film (or in this case a combination of the two), I’d probably give the spelling a quick check before the design was finalized.
Not so the makers of a rather colourful baseball cap I came across recently. As is always the case in these situations, I didn’t have a digital camera with me. Having to make do with my rather limited camera phone. But that said, the design’s glaring error is still clearly visible in all its misspelled glory.
