Pitcher Hiroshi Kisanuki is on top of the wrapped deck, thus the only visible card (of wrapped deck). Looking at their roster, I see that he was not on the Giants in 2010 but was for the others years in question. So 2010 is out.
Another image I found was of Koji Uehara and Shinnosuke Abe. I knew Abe was on the team for many years (2001-2019) and was of no help. I knew Uehara played in the MLB but didn't know much else. I looked at his BR bio and it shows he was on the Giants from 1999-2008, he went to play for the Baltimore Orioles in 2009. Thus this card set cannot be from 2009.
So this leaves 2006-2008.
Lee had two different numbers while with the Giants. In his first year, 2006, he wore #33. In the other four years, 2007-2010, he wore #25. In this deck he is wearing #25.. so 2006 is out.
Looking at other images I've found online, it's too hard to determine the names or players on the rest of the cards. Can you help determine if this is a deck for the 2007 or 2008 Yomiuri Giants?
I am not sure when I will receive the deck in hand from my friend in Japan but wanted to determine ASAP because these two Lee cards will then need to be sent to friends in the US for a PSA submission.
UPDATE: A few hours after posting this, I think I figured it out. I zoomed in and saw a foreign player (#42) too light-skinned to be Marc Kroon. I looked up Kroon and he wasn't a Giant in 2007. I looked up the 2007 Giants roster and I saw Jeremy Powell listed with #42. He was on the Giants in 2006 and 2007 seasons. Kroon came to the team in 2008 so I'm sure this is a 2007 set and I will go with that.
