Don't worry, I won't be going on a longwinded, angry rant. I just want everyone to know that if you have ever purchased a print, tshirt, mug, badge, ANYTHING with my work on it... the seller has not recieved permission from me to profit from those items.
I am perfectly happy to let people print these pictures I've done, for themselves, or friends. I encourage it! However, I do not like that people have... and still do, use them to make a profit for themselves without having contacted me first.
If you see my work for sale on a website, or at a convention, I can't stop you from buying it. But I would encourage you not to, as the person selling it really has no right to. If they tell you they are the original artist, or that they got permission, they are LYING.
