Vintage Rock Rose Yellow Lidded Sugar Bowl And Creamer

This is like Blue Ridge Southern Potteries, but not back stamped. Rock Rose Yellow Creamer and lidded Sugar Bowl is from the 1950s. The creamer measures 3" H x 5.5" W. The sugar bowl with lid measures 3" (with lid) 5" H x 7.5" W ( including handles) This pair is stained, I bought it that way. It looks Folk Art to me.
