The main Granderson in the set is part of the "Spectrum Swatches" series, that looks like this:
Granderson with a glove (finally!), shinyness, gray swatch, you get the idea. These cards have a number of parallel versions. There is the main version (teal? turquoise?) numbered to 99. In addition you have:
Orange (#/75)
Green (#/50)
Red (#/35)
Brown Auto (#/30)
Purple (#/28)
Lt. Blue (#/15)
Green Patch (#/15)
Lt. Gray (#/5)
Dark Gray (1/1)
Even in slightly incomplete form these look pretty sharp together, don't you think?

Other than that slew of multi-colored game used parallels, there is one other card in the set--a Dual Spectrum Swatches card with Magglio Ordonez #/99. I have no idea what this looks like and don't really want to know. I know that sounds spiteful, but a lot of people spent a lot of time hating on Spectrum and based on the one card (and its variations) that I have/have seen, I don't mind it at all. I'm sure things would be different if I were exposed to the whole set, which is why I'm apprehensive about finding that Ordonez/Granderson card.
Anyway, that's my two cents on Spectrum. For the sake of other collectors out there I hope that they improve their set in 2009, but for my sake, just give me some nice looking Granderson cards and I'll be fine.
