I have a booth at an antique mall, or more like vintage/upscale thrift mall type of place. The other day I noticed the owner had put this into her booth! Whoo hoo!
It's a Balloons Promotional Cinderella bowl. It was part of a chip and dip set and came out in Spring of 1958.
She did have the dip bowl as well, but unfortunately it was dishwasher damaged beyond repair.
That's okay. I'd still have to find the bracket. For now, this is pretty cool for my turquoise Pyrex collection!
