Vintage '50s Oven Ware USA Turquoise Drip Glaze Pottery Serving Bowl No.54

Description

We're cleaning out my nieces' other Gram's house. She was 93 and passed away in March 2020. She was a Fuller Brush/Stanley dealer for many years.
She and her husband Carl, who passed 3 months before her, were the salt of the earth. Her name was Doris but you can call her Gram. She saved everything, as most people that lived through the depression did. This is from Gram's closet. Please use it with love.
This Oven Ware (Watt?) No. 54 serving bowl is 8 inches across by 3 1/2 inches deep.
It does not have any chips.
THIS BOWL MAY HAVE BEEN A SECOND; IT HAS 2 IMPERFECTIONS IN THE GLAZE: SEE PHOTOS 4 AND 11. THE SPOTS IN PHOTO 4 ARE NOT CHIPS.
THERE ARE SOME CIRCULAR CRACKS IN THE GLAZE INSIDE THE BOWL. SEE PHOTO 10
Please see all photos.
