Over the centuries, stone masons have been known to chisel their unique, distinguishing mark into a stone, leaving their signature for future generations. Moving forward in time to the past century, concrete has become a prolific construction material.
Here in Toronto, I have discovered that sidewalk installers have been keen to embed their “signatures” in freshly laid concrete. Here are a few examples of modern day concrete markers, indicating the dates when the concrete was installed. These are my submissions in response to Cee’s Black & White Photo Challenge: Numbers for this week.
For the budding urban archeologist, these sidewalk markers can be used to determine the dates of previous infrastructure upgrades, and identify the businesses that were active in their trade at that time. Anyone interested in doing some sidewalk rubbings?
Numbers in cement. Well seen and taken. Thanks for playing.
