I just got these yesterday, a gift from a friend. It's some sort of promotional material from the POTC online game, which I believe she got at the Pirates showing at the El Capitan in Hollywood. There was a Beta disc (which my brother will get to play with) as well as this litho (game artwork?) inside the envelope.
Since we're on the subject of pirates, I picked these up at Disneyland a while back. I really like the artwork they did for the playing cards, based on the ride, of course. The keys I thought were useful as a prop for school. They appear to be made of metal, they're pretty heavy.
