Edit: I made an agreement with the person in charge of that project, and he compromised to give me a remuneration for the use of my image and not use my drawing again, also they want to work with me, lol.
Thanks to everyone for the help and the support. ----
Hi everyone... Since long time I don't write here... I hope everyone is ok~
I'm having a problem, some peruvian friends told me that they saw my art in some notebooks in Peru, and a friend just show me this:

So this
"Folbook Cuadernos" is stealing my art
[link] and selling it as notebooks in Peru...
Nobody asked for my permission, this is so outrageous...
I wanted to know if someone knows how to deal with this kind of things?... I'm thinking of speak with a lawyer... but if someone can suggest anything better, I would be grateful...
Thanks for your attention.
Kura~
