I don't know for sure that the Matsubara card is from this set - it is not in Engel's listing for the set. It could be from one of the other 1976 blank backed sets (JY1 or JY1c) but it's not listed there either - there's another Matsubara card listed with JY1. As Engel points out, these sets are very confusing.
Engel lists the Oda card simply as "Fighters vs Buffaloes - action shot". I wouldn't have known it was Oda if the seller hadn't included the name in the listing. The Buffaloes pitcher is Toshio Kanbe. You can tell the card is for Oda because the copyright line at the bottom says "Nippon-Ham Fighters"
