BBM seems to have wrapped up its Achievement series, at least for the time being, after issuing two sets in December labeled as "2015" issues. One of those two features the Whales.Braves and Hawks sets, with different border and card back colors. The images look grainy, similar to the effect Topps uses with Heritage. There are 30 cards in the set.
There is a foil-signed partial parallel, Printed Autographs. There are 22 cards in that set, each serial numbered to 48 or 50 copies.
3000 sets were produced and sold in boxed form with one printed autograph or hard-signed autograph per box. Retail price was 4000 yen, but it seems like the Whales set hasn't sold well, and I've seen a couple around 2000 yen on Yahoo! Japan Auctions in the past couple weeks. Singles haven't appeared frequently on the auction site either.
