I turned down a block I don’t usually visit on my walks because there were some Christmas lights I wanted to see. I was rewarded twice, with the lights and with this very well preserved Department of Public Works stamp. This is the east side of Allen Street, just south of Elizabeth (the last block before I-496).

This is from that period after they stopped stamping the exact date but before they dropped the month too.
Looking north on Allen Street, with Elizabeth in sight.
