Blue ceramic coffee mug set (2) with chip

I found a set of two blue ceramic coffee mugs this afternoon around 2:15 PM in the parking lot behind the Port Huron Public Library on McMorran Boulevard. They’re sturdy mugs with a glossy cobalt glaze and white interiors, each about 3.5 inches tall. One mug has a tiny chip on the rim, and there’s a faint coffee ring on the other, but otherwise they’re in good shape. They probably belonged to someone who uses them daily and was bummed to lose them, so I’m posting here to help reunite them with their owner. If these are yours, tell me the chip location and we can meet near the library’s back entrance to hand them over.
