The base set contains 99 cards, split into four subsets. The first subset is a six card "History of Giants". Each card covers a different time period in Giants history with a picture on the front from the time period. Each time period has a different name on the card (in Japanese so I'm relying on Google translate of Jambalaya's page for the set) - "Dawn Of Giants" (1936-44), "Second Golden Age" (1946-1960), "V9 Giants" (1961-74), "From Slump To Glory" (1975-88), "March Of The Giants" (1989-2001) and "21st Century Giants" (2002-2014). Here's the "From Slump To Glory" card ("slump" referring to the Giants sole 6th place finish in 1975):
There is a notable lack of foreign players - only Wally Yonamine and Alex Ramirez are included in the set. Warren Cromartie is probably the biggest foreign player omission but Tuffy Rhodes wouldn't have been out of place in the set. I was kind of surprised to see that Kazuhiro Kiyohara was not included in the set. I was less surprised to see that Hiromitsu Ochiai and Masaichi Kaneda are not in the set as Ochiai has not appeared on a baseball card since 2011 and Kaneda doesn't show up very often.
The photos used in the subset are pretty good. Most of the players are depicted in a photo that I don't think has been used for a card before (with the exception of a couple of the older players that there simply aren't many photos for). I knocked BBM's 80th Anniversary Batters Edition set the other day for having a pretty generic picture of Sadaharu Oh - this set makes up for it:
