Vintage Pottery Pitcher Mugs And Creamer With "Marilyn" Bottom Mark

I really think that this was the buy of the day today, 9/9/18, at the Flea Market, it's a beautiful Ice Tea Set? with a Pitcher, Creamer, and 7 Mugs. The Black Glazed, Brown molded clay, pottery Set, looks to be from the 1940's-1960's, and looks to be used very little, if any. It's probably missing a Mug, and maybe a Sugar, but looks to be like new. All the pieces are marked hand written into the bottom, Marilyn, and no other marks. The Pitcher is 9 5/8" to the top of the spout, and 6 1/4" from the back of the handle to the front of the spout, and has a 2 1/4" base. The 7 Mugs are 5 7/8" tall, and 2 1/2" across the top, with a 2" base, and are 4 1/2" at the widest point. The Creamer is 5 3/4" to the top of the small 1/2" spout, it's 3" at the widest, and has a 1 5/8" base, and it has a pinched sides grip.
I really think that this is a factory made set, but could find no information on Marilyn Pottery/Ceramics.

Thank you for looking, any information, or ideas, about who, or when this Set was made, is appreciated! All comments are welcome! :^)
