I look for abstracts to be found in the urban and rural landscape of decays, dents, peeling paint and paper, and any kinds of wear and tear.
Here are a few found in Niagara:
Dents on a sign at the Lake, Vineland Ontario.
"Abstract in Yellow"
Decay in cement:
"Red Moon Blue"
Glue remains on a wall in St. Catharines after the signs are gone.
"Even Strokes"
