This is a Japanese (or English) language manga (comic) or a magazine featuring multiple manga series.
Shueisha is reprinting the Dragon Ball manga in a large format, with new covers, and with the colored pages from the original Weekly Shounen Jump magazines reprinted in (drum roll) color! The covers are new as well -- in the background is a piece of art from the original manga, and in the foreground is a character done in Toriyama's more recent style. The differences are quite striking, and it's a great effect (especially for those of us who watched his style change slowly over the years!). Please note that these are simply reprints of the original manga, and there is no new material, and the text is all in Japanese (no English translations). Most of the art is in black and white (though having the colored pages, finally, is a great joy to those of us who collect the series!). An absolute must for fans of Toriyama or even just of Dragon Ball!
