Vintage Bay Pottery & Thick Glazed Gradient Blue Green Ceramic Pitcher

I’m not sure how old the taller pitcher actually is that I’ve had since the 1990’s.The mixture of blue colors in a peacock like pattern is really unique.There’s some green toward the top that reminds me of a mallard duck.Whoever made this did a beautiful job combining these colors in a real thick glaze..Does anyone have any idea who signed this.? With it is a Bay pottery salt glazed pitcher and a 1960’s creamer made by Arrow pottery in Japan.Thanks for looking.
