I had never seen it before and was not even sure what the base cards looked like, so I figured I would give it a try. I was pleasantly surprised.
I scored two Legendary All-Stars: Nolan Ryan and Bob Gibson.

Here is the back of the Legendary All-Stars card, which is similar to the next subset of cards: All-Star Futures.
Here is a really nice looking Joe Mauer All-Star Futures:
Now a much less accurate prediction of All-Star Futures: Oliver Perez.
If you, like me are a Met fan, you are quite upset with Perez's unwillingness to go down to the minors this season to work out his mechanics. You also hope that he is not in a Met uniform next season.
The other four cards were normal base cards.

Here is the front and back of a Gagne card, remember how dominant he was?
The pack finished up with an Alfonso Soriano, Miguel Tejada, and Randy Johnson.
For me this pack was definitely worth it: good players and an interesting design I had never seen.
Hope you enjoyed seeing them too!
