I agree - pacifier addict, which is Rearz. That's their size 6 adult pacifier, with a print on it - but you can customize them, so it may be something someone ordered, rather than something they list.
I was going to get one with a Pampers logo on it when I was there in person a couple of years ago, but whereas the pacifier costs like $5, adding the print brought it up to $20 or something... not worth it to me. I have like 25 of them already. But if you find that image and go to them with it, they can make that for you.
