Sunflower ceramic vase found near Santa Maria library

I found this sunflower ceramic vase this afternoon around 4:15 pm behind the Santa Maria Public Library, near the parking lot off S Broadway. It’s about 7 inches tall with a cream glaze and hand-painted sunflowers in bright yellow. The glaze is glossy with a subtle crackle finish, and there’s a small chip on the rim that I could feel when I picked it up. On the bottom there’s a pencil inscription that reads 'S. Rivera 2019,' so it might be a personal piece. It seems well-made and has a nice charm, and I’d love to help reunite it with its owner—if you can describe the inscription or the chip, I’ll arrange the return.
