This is a vintage midcentury modern Norsk Tinn Pewter creamer and sugar bowl with a blackened and embossed fern band. I do not know the pattern name. Each piece is marked Norsk Tinn Pewter on the base. The sugar bowl has a small dent on the bottom rim. The sugar is 2 7/8" wide and 2 1/8" tall. The creamer is 2 5/8" tall.
