Ceramic wall pocket

This wall pocket is about 9 inches in diameter and about 2 1/2 inches thick at its widest point. It is large for a wall pocket. It has the label of a Peoria, IL flower shop that was founded in 1945 and is no longer in business, the Knollaire Flower Shop. It is in really nice shape and has a bit of cracalature on the back, but not on the front. The pistil in the center of the flower is made up of many little ceramic filaments. Not signed and not marked. This could be 1950s American or Japanese made. Just a guess. A $2.25 thrift shop find.
