Lost blue and white ceramic antique vase with intricate floral designs near parks around Lake Charles.

I recently misplaced a beautiful antique vase that belonged to my grandmother while visiting the parks around Lake Charles. It is blue and white ceramic with intricate floral designs and approximately 12 inches tall. I last remember having it in the car after a picnic, but I'm afraid it may have fallen out while loading things back in. I would really appreciate any help in finding it!
