Found ceramic coffee mug with blue glaze and chip

I found a ceramic coffee mug this afternoon around 2:45pm near the public library on Main Street in downtown Del Rio. It's a handmade mug with a deep blue glaze that fades to teal toward the bottom, about 12 oz capacity, and a chunky, easy-to-hold handle. There's a small chip on the rim, and a faint coffee ring on the inside bottom. On the bottom, there's a tiny stamped heart and the initials 'ML' that might help the owner identify it. It looks like it meant something to someone—it feels wrong to keep it—if you're missing a mug with a blue glaze and a little heart stamp, I hope this helps get it back to you.
