Found ceramic mug with blue glaze near Main Street Deli

I found a ceramic mug this afternoon around 3:15pm in the plaza behind the Oneonta Deli on Main Street. It's a medium-sized white mug with a hand-painted cobalt blue glaze swirling around the outside, and there's a small chip at the rim that shows the ceramic underneath. The handle has a slight scuff from daily use, and there's a faint coffee stain inside. I figured it might belong to someone who uses that mug as part of a gift set, but I couldn't see any brand name. If this mug belongs to you, please reach out with a way to verify the unique chip on the rim and the blue glaze pattern, and I'll arrange to return it.
