Like all artists, all my created work is Copyright protected.
This means that nobody has the right to reproduce my paintings without my consent.
Artists or amateur artists, students cannot copy my paintings.
They surely are not allowed to copy and sell under their name. It will end up in tears.
They are not allowed to do cards or prints of my work.
Illegally copied work of mine, will be found out. I have been an artist for over 3 decades and my work is known by my followers who can spot a scam and inform me about it.
So what would happen? I will take legal action, asking to the person who copied my work for all the money they made reselling it plus compensation.
