The Thor's hammer (icel. Þórshamar) is an ancient magic symbol used to find out if someone has stolen from you.
That is the reason why we choose this symbol. Our aim is to provide art who is not overly priced and appeals to everyone. We're not going cheat anyone or exploit, because it is in the meaning of our sign the Þórshamar.
It is not any less to rebuild the former glory of the Swastika, the great symbol of the sun, who was poisioned in the thirties during last century under National-Sosialism (nazism).
Here is talked about the Þórshamar on Wikipedia and here is the magic recipe for the symbol(in icelandic).
