Rich Hill, he of my favorite baseball PC, has 11 cards in the 2008 Bowman and Chrome sets: one each of the base, then nine colored parallels between the two. Besides that he's got 10 1/1s available as well in the form of four plates from each set, then a "true" 1/1 SuperFractor and base Red parallel. As I've seen others do, I'm showing off the whole non-1/1 group plus a 1/1 since I have one, but I think it's up to every collector to decide for himself how he defines a "rainbow."
Here's all 12 cards I have:
- Bowman base, Chrome base, Bowman Gold parallel
- Chrome Refractor, Bowman Blue parallel (#129/500), Bowman Orange Parallel (#008/250)
- Chrome X-Fractor (#139/250), Chrome Blue Refractor (#047/150), Chrome Gold Refractor (#27/50)
- Chrome Orange Refractor (#12/25), Chrome Red Refractor (#1/5), Cyan Printing Plate (#1/1)
Definitely not a bad group. In terms of the parallels I give the edge to the Red Refractor, not because it's so rare (plus my copy is #1/5), but because I think it ends up looking the best. Ordinarily my money would be on the Blue Refractor, but Topps didn't use a dark enough blue in this version. Finally, bonus points to the Orange Refractor for having a Christmas serial number, of which I'm sure Gavin would totally approve. Please leave me a comment telling me which is your favorite.
