Antique Millersburg Glass Company circa 1912 Rich Marigold Nesting Swan Pattern Ruffled Carnival Glass Bowl.  TOP EXAMPLE.  Iridescence is spectacular.  The bowl is 2 3/4" at the highest outside edge and 10 1/4" across the longest.  The only minor thing is a nick or rough spot smaller than a pin head on a edge point.  You really only notice it by touch.  Auctioneers call these flea bites and expect that it is an insignificant event when selling items such as this.
