Upper Deck has just released a set of Trading Cards on Disneyland's 50th celebration. There are chase cards and other goodies as well as the regular trading type cards that Upper Deck is so famous for.
www.UpperDeckStore.com When you get to this page, just scroll down a little and you will see the big ad for the cards.
The box of cards (which is not all that expensive in the long run) is the easiest way to get a complete set and some of the chase cards. Then you can either give the rest to kids or other Disneyland fans, or keep them. My set is on the way and is scheduled to arrive tomorrow. The site has pictures of the box and a complete description of the cards and goodie cards.
