Vintage Frederick Cooper stamped (171) trinket bowl with lid

Really beautiful pastel hued enamel ceramic trinket bowl from the 70s. Listing this for my mom. She’s enjoyed it thoroughly for many years and is now ready to let it go. It is a vintage piece with natural wear for its age. There are NO major flaws such as cracks or repairs. Hoping this connects with the right new owner it really is a stunning piece. Measures approx 8” diameter by about 2” in height.
