An early pour

I've gained back the weight I lost over the summer - I'm back up to 220 Lb. I falter occasionally with my daily exercise and walking routine. I've set a daily alarm on my iPhone to remind me to take a walk and do my exercises.

On my walk this afternoon I became aware of the stamps embedded in some of the concrete sidewalks. I see these everyday but have never looked closely at them. All of the stamps have the name of the contracter that did the work and most have the year the sidewalk was poured. Most of the sidewalks in the neighborhood were laid down in the late sixties and early seventies. I was startled when I turned the corner and found this stamp:

Good golly! This sidewalk is older than I am.
