Enameled Periwinkle

I'd not heard of this pattern on decorated Carnival before this pitcher and two tumblers sold in a Seeck auction in 2013 for $225.

This water pitcher, different in both design and decoration, sold in 2014 and was also listed as Periwinkle. It brought $150. Two similar pitchers, each with a tumbler, sold in 2014 for $175 and $200.
