I generally don't like parallels. The card companies have overused it, and it makes collecting a hassle. I did find a parallel I liked, and I think it's one of the few instances where the parallel greatly improves the base set.
|1992 Leaf - Black Gold #302 Randy Johnson|
Let's look at the base set for comparison:
|1992 Leaf #302 Randy Johnson|
It's ugly. Gray (or grey if you prefer) is a bland color for a border. It didn't work well for 1989 Fleer, and this is no different. The parallel looks sharper with the black border and excellent use of gold foil trim. To be honest, I don't even mind the lack of the team logo. Even the back of the cards are better:
|1992 Leaf - Black Gold #302 Randy Johnson (back)|
|1992 Leaf #302 Randy Johnson (back)|
Again, boring gray is replaced by a nicer golden color. Leaf should have made the black border the base set and left it at that.
