This is a book from Japan (written almost entirely in Japanese) that I purchased recently (and is still available). It's basically a price quide for 1970-1980s electronic games (even though it's a Japanese book, the prices are listed in dollars). It features hundreds of the classic handheld games released in Japan, the US and the UK, and also some of classic console systems. (Complete book should have a full color dust-cover (seen here) and green obi-strip.)
