Got pictures of the Mad Hatter hat(s) they sell at WDW?

[TigerB]

We are going to MNSSHP this year (YAY!!) and we are doing an Alice in Wonderland theme. I was wondering if I should just buy the Mad Hatter hat when I get there, or pick it up before we leave for our trip.

Does anyone have pictures (or a link to a picture) of what Mad Hatter hats I can expect to find at WDW? We don't need it until our 4th night there...so I have plenty of time to pick one up at any of the parks/Downtown Disney.

(PS: If you could also let me know which store/park you believe the hats to be at, and the PRICE, please let me know! I want to know if it'd be cheaper to get on eBay ahead of time.)

THANKS!!
