Hand-painted ceramic vase with koi motif

I found this hand-painted ceramic vase this afternoon around 3:15 pm along the Fort Pierce Riverwalk near the public pier. It's about 10 inches tall, glazed in cobalt blue with a koi motif in emerald green and gold specks. There's a small glaze crack on the rim and a tiny signature 'M. Alvarez' on the base. It feels like a small piece of art that could've been a gift, and I figured it belongs in someone’s home rather than my shelf. If it looks familiar, email me at [email protected] so we can figure out how to get it back to its owner in Treasure Coast.
