This is the catalogue book from 絵師100人展 2012 (100 illustrator exhibition). 絵師100人展 is an event where 100 artists display their artwork in exhibition with the theme "the four seasons of Japan" that took place in Akihabara UDX Akiba Square around golden week (end of April to first week of May). They sell limited edition of arts and goods during that event. It's pretty cool. You can even meet the artists and get their autograph. More info about 絵師100人展:
