When I found this artwork online I contacted the artist to see if I could use it. They were more than happy to let me. I worked with another artist to colorize the artwork and add some additional elements there were not in the original artwork. I took the theme to the back of the coin and think we have another great series for your collection.
The forth is 'Air': The colors in this are outstanding and the artist has done a nice job with the limited blues at making the water and air very different.
