This “second style” Department of Public Works stamp is on the north side of East Saginaw Street between Maryland and Marshall (closer to Maryland), in front of Marshall Park. My husband and I walked to the park tonight because I heard that the city fireworks can be seen from there (pretty well, it turns out).

Looking east on East Saginaw with the stamp centered above the nearest sidewalk crack. The sparkles near the center of the sky are amateur fireworks going off in the distance.
