This is a great piece of pottery that dates to 1950's. It is green ceramic with a wire floral frog (flower frog) in the center. There is no maker's mark but it likely is a piece of California pottery that was very popular in the 40's, 50's and 60's. It will hold several flowers upright in any container you place this in or use as is. It measures 4" diameter and stands 1 1/4" tall. From my personal collection.
