There is a con in Japan called Comiket. This con is held twice a year. There are like a hundred of circles/booths that sell their merchandise.
I wonder how much cost for the production of their fan-made manga and artbook/illustatrion book.
- The price for a doujinshi manga is around $20 - $40 based on this site
- The price for illustration book is around $15 - $50 based on this site
according that, how much the production cost ?
