Have a look at this site www.sandawe.com
This site targets the BD-lovers (it stands for bande dessinée or comic strip in French).
They can invest in 10€-shares on their favorite projects.
As return, they get up to 60% of the profit, the book signed by the author(s) and their name is printed in every copy as a thank you…
This is called “crowdfunding”, which they are the first to implement in this field.
