For this illustration, I needed to describe a magical transaction so I took a roman coin and a new 5 pence piece and switched the age of their reflections. Turns out it's remarkably difficult to get a wafer thin, almost two thousand year old coin to stand on its edge but I managed it.
 
The drawing comes complete with a copy of the story by Sean Walter. 
 
Worked in charcoal and Wolff's carbon pencils on Fabriano Artistico extra white paper. It's framed ready to ship in a smart black frame made using recycled materials and with acrylic safety glazing. Drawn area size 12" wide by 18" high, frame size 16" x 22".
