1997 was also an important year in the hobby because of the advent of the 1/1. I sure wish I had one to share, but the 1997 Flair Showcase set featured an interesting structure that included the first ever true 1/1 parallel: the Masterpiece.
The set consisted of 180 players on three different levels (called Rows), with each row featuring a unique front design. In order of rarity, from most common to most rare, there was Row 2, which was titled "Style," Row 1, which was titled "Grace," and Row 0, which was titled "Showcase."
Additionally, each row was sub-divided into three 60-card sub-sections featuring a different cardback icon. The "Showtime" cards featured a baseball icon on the back of the card, the "Showstopper" cards featured a batter icon on the back, and the "Showpiece" cards had a glove icon. Each player had one card in each of the three rows, meaning each player had 3 base cards total, the Showtime being the most common, and the Showpiece being the most rare.
Each base card had a Legacy Collection parallel numbered /100, regardless of row. So each player had 3 Legacies, one for each row. Each card also had a Masterpiece 1/1. The Masterpieces had purple foil, instead of the blue foil of the Legacies, and said "The Only 1 of 1 Masterpiece" on the back.
Here is the Row 0 Larkin:
And here are the Row 1 and Row 2 Legacies:
I personally think the Row 1 and 2 look the best. They are clean and crisp. However, the Row 0s are much more desired in the market.
