I got this link to the OS from the latest Delta Source. Looks to be a very eclectic set. Only 51 base story cards with a bunch of other goofy styles mixed in. It's definitely interesting and I'll be collecting the whole set. Hopefully we'll also get a Widevision set down the road as well.
I do like sketch cards but not at the expense of autographs. I'm afraid Topps is taking the wrong path since the AOTC Widevision when it comes to the premiere inserts.
