The cards themselves are pretty basic. The fronts are borderless color photos and the backs are blank (except for the occasional prize notation). Probably more than most bromide cards, these feel more like photographs on heavy paper stock than baseball cards. The cards are a little longer and narrower than the standard size - about 2 1/4 inches by 3 3/4 inches.
Engel lists around 40 cards in the set. I got 32 unique cards out of the 32 packs in the taba, so I now have roughly 80% of the set (although I am not positive that all the cards I have match cards Engel lists - I may have a couple uncataloged ones).
Player selection for the set is a bit odd. Only eight of the 12 teams are represented in the set - Chunichi, Hanshin, Hiroshima, Kintetsu, Nippon Ham, Seibu, Yakult and Yomiuri (so no Hankyu, Lotte, Nankai or Taiyo). Five of those teams (Chunichi, Hanshin, Hiroshima, Kintetsu and Nippon Ham) are only represented by a single player. There are 18 Seibu Lion cards in the set but three players (Koji Akiyama, Kazuhiro Kiyohara and Kimiyasu Kudoh) are on 13 of those. There are 10 Giants cards but six of them are Tatsunori Hara or Masumi Kuwata. Finally there are seven Yakult Swallows cards and six of them are of Kazushige Nagashima (Shigeo Nagashima's son). 1988 was the younger Nagashima's rookie season so this is one of the few times that cards were made of a rookie player.
For the most part the photos on the cards are pretty good. Here's some examples:
I suspect but I'm not positive that the cards that have text on the front are unauthorized copies of Calbee images. I also suspect that at least a couple of the cards without text may be unauthorized copies as well.
