A weird glitch

I can't blame you guys, since I approved the proof without noticing the problem, so I have to take responsibility. But I don't really understand how it happened. If you look at the red sticker that's second from the left, second from the top: there's writing missing from under the image of the dragon. I checked again and it's definitely there in the file that's on my computer, which would have been the file I uploaded. So I don't know how it went missing later. Bummer.
