As you might expect, the Eagles are the last NPB team to get an Anniversary set from BBM - this is probably the first anniversary worth noting for them. I'm a little amused that they got a 90 card, pack based set when Orix only got a 55 card box set for their 20th Anniversary in 2009 (BBM has released a larger set for their 25th Anniversary).
The first 74 cards in the set are devoted to OB Eagles. As usual, "OB" in this case means both retired players as well as former players still active in either NPB or somewhere else. Some of the players included are Takeshi Yamasaki, Akinori Iwamura, Hisashi Iwakuma, Norihiro Nakamura, Jose Fernanadez, Kazuo Fukumori and Fernando Seguignol. One notable inclusion is Keiichi Yabu, who briefly played for the Eagles in 2010 (basically 11 games between August 10 and September 4) after playing in North America for five years after leaving Hanshin following the 2004 season. This appears to be the only BBM card depicting Yabu with the Eagles (the only other Japanese card showing him with the Eagles was a 2010 Owners League card). Off hand there's no one obvious missing although there are some questionable inclusions - Hironori Fujisaki for one, who never appeared in a BBM flagship set after his rookie year of 1999 (with Kintetsu) and only made 26 appearances with the ichi-gun Eagles over a three year stretch with an ERA of 6.14. Katsunori Nomura, the poster boy for nepotism in NPB (he is Katsuya Nomura's step-son) is another questionable inclusion.
Here's a couple of the OB player cards:
As usual, Ryan beat me to posting about the set and you can see all the cards at Jambalaya.
