Hand-painted koi porcelain vase

Found a hand-painted porcelain vase this morning around 9:15am behind Capitol Market in Charleston, West Virginia's Old Market District. It's about 8 inches tall with a slender neck, glossy cobalt blue glaze, and delicate gold trim along the rim. A running koi fish motif circles the body, and there's a tiny maker's mark on the bottom that looks like 'A. Lin.' The rim has a small chip, and there are a few age-related crazing lines in the glaze. It feels like a special piece—maybe a gift—and I’d love to see it back with its owner if you recognize it.
