The Dark Knight Stamps on the Joker cards

[lochneffmonster]

I've noticed each city has differant stamps on their Joker cards from the most recent scavenger hunt. Are they a clue?

I just got back from Chicago. Man I am so tired from that drive. My card had a stamp of "J" on it and nothing else.

 

[Screwpa!]

Seattle has a swirly on it. Helpful, I know.

 

[Nebins]

I can't tell what mine is. It looks like smudged swirls.

i'm not sure we have to really do anything with the symbols. i think they were just to verify that they were real joker cards so we can get into the theater. the theater i went to actually asked to see the stamp from everyone getting a movie ticket. however...
the toronto one has a red star.... pic up in a moment...

KC we didn't have to show anything to get in. They seem way to random to mean anything, but then again...

Here's the cards I got today, some friends didn't want theirs. These are mine and for my bro, sis, and friends. Not for sale... maybe trade, sorry.

They're in order of my favorite starting at the top left.

If you turn it upside down, it looks like a Jester hat.

The one I got in toronto is a bit different than the other ones in that it has no figure on the card but the word joker all over the card.

I actually got the joker card you see at the end of Batman Begins and the London stamp is a kinda rip off of mickey mouse
