These tiles are approximately 6" x 6" or close to it... Collectively they make up a 4' x 4' piece.  Every single outline in black is actually a 1/8" cut into the roofing paper. Paint is rubbed into the paper, a sketch is drawn, the design is cut, re-painted and then re-tooled... It is very textural and approachable. 
I ve ridden my bike across the USA, hold a couple of records and have completed over 170 various races.... 
You;d think that I would have produced more art about cycling...?
