Thank you to all of you for informing me about Hidden Supplies
, it seems that they have taken one of my images along with many other fanart from different artist and was selling it online as well as at conventions.
At first I was really mad and pissed, but then I learned that they apparent gotten permission from some artist to sell their works there. I can't speak for the other artist that had their works sold by them as some clam that they did give permission for their art to be sold by them. But I feel that there might be other stolen works other than mine, since they didn't contact me for permission.
I'll contact them about it, and ask them to take my work down, if you recognize some of the artworks that are on display, inform the artist and see if they gave permission or if its stolen : )
Thanks to all of you for contacting me about it, and thank you yuumei
