2 VTG “Philip” solid copper enamel bowls

Pair of signed “Philip” vintage copper enamel trinket bowls or coasters for wine or glasses are slightly less than 5.75” in diameter. Lovely pink and green tones on one and teal to turquoise tones on other. The design on each is raised and considered three dimensional. Elements suggest the Brutalist style. There is a flaw in enamel on back of the teal bowl as shown in photo
