I have to agree with Steve on the minor league cards. The design and colors on those are so nice.
Matt -- as already mentioned, one of the keys to finding a sharp card is registration. Registration can be all over the place on this issue.
On the Cobb, for example, the red infield can sometimes be shifted a bit, which is not uncommon. Another thing to look for is the brown coloring within the two bats on the Cobb card, which can often be slightly off register.
Cobb, Matty, Zach Wheat have all been mentioned, and are all beautiful cards, but another standout is the Home Run Baker -- just love the blue/gold color combo on the A's cards...
