I managed to find this image of the style guide used for Japanese "SegaSonic the Hedgehog" products from 1995 onwards on an old Metal Sonic fansite. The majority of this artwork is unique and has rarely ever been reused (its most notable new lease on life was the Stray Rats fashion line). Has anyone else seen images from or (knows somebody who) has this guide? Anyone seen any Japanese brand guideline books show up? If you have or if there's a term I should be searching for, I would love to know. Page appears to read "Artwork on disk and positive film" so it would have come with a CD and 35mm slides/transparencies. Sonic Origins contained six pages from a SegaSonic style guide, but this only covered the first few years of the brand. Sonic Mega Collection includes an illustration of Sonic from the style guide.
