This is an official Japanese anime notebook featuring three different series which are all based on games/manga owned by Enix. Violinst of Hameln, Mahoujin guru guru and the Dragon Quest (dragon warrior anime) In addition to the full color cover the inner pages have monochromatic blue images featuring the same characters. This was apparently from a GW Animation Festival in 1996. We can’t find any information about the festival so we don’t know if it was a con or a an ad campaign or something else. Either way this is a fun vintage anime collectible.
