Much like the No-Hitters set BBM issued in 2012, the Perfect Pitching set came on the heels of what remains the last recognized NPB perfect game. Hiromi Makihara of the Yomiuri Giants beat the Hiroshima Carp 6-0, striking out seven batters on May 18, 1994.
Opening the album, or really, giant card holder, reveals three cards honoring the game, including a celebratory photo and three cards.
Inside are cards for all fifteen perfect games thrown in the NPB. On the far right, a placeholder (really just a sheet of paper) is included for Tsutomu Tanaka, for whom BBM could not get the rights.
The back includes the photos found on the card fronts. You can see the original retail price was 2000 yen.
Before you say anything, yes, there was a perfect game pitched in the NPB after 1994. In 2007, Daisuke Yamai and Hitoki Iwase combined to throw a perfect game in Game 5 of that year's Japan Series against the Nippon Ham Fighters. However, NPB does not recognize combined no-hitters, so as far as the record books are concerned, Makihara was the last pitcher to throw a perfect game.
I initially bought this set with the intention of using one card for my type collection and a couple cards for other collections. However, since it came complete in this nice folder, I haven't broken it up. I'll have to stay on the lookout for singles or another set. (And a real card of Tsutomu Tanaka, who apparently only appears on a Kabaya-Leaf card.)
