These copper medallions are printed with my original drawings.
This process requires first drawing the design on brass, then etching with a chemical solution, essentially creating a 'print block' and using that to print onto a softer material, by running through a roller press.
The results are beautiful and vary slightly on each piece. 
Some pieces I add patina or chemichal solutions to enhance the design and bring out the textures.
Enjoy!
The copper is sealed to prevent discoloring on the skin
