Produced by Millersburg Glass in the early 1900's, this is the Blackberry Wreath pattern on a 8" ruffled, green carnival glass bowl. The iridescence is very nice on this green carnival glass piece. There are similiar patterns, Strawberry Wreath and Grape Wreath, also produced by Millersburg Glass. The Blackberry Wreath pattern can be distinguished by the leaves and a berry at the center of the pattern. Leaves in the pattern may vary between three and four. Millersburg produced quality pieces and this Blackberry green carnival glass bowl is a lovely example of their work.
