Mason's mark 

I designed my own mason's marks in these five mixed media artworks on black paper.
The Mason's Mark is an ancestral engraved symbol. 
It is usually found on dressed stones in built structures - as a signature or meaning about the work done.
Typically, the signs consist of 4 symbols: a circle, a triangle, a square, and a diamond.
As they are to be seen in the approaches to towns and cities, I applied their meaning and their use to create these abstract maps.
I follow the same process and I inscribed marks on the paper with the back of the brush into the wet paint.
