RARE Vintage Blue Danube China Snack Plates - FOUR. Pristine condition

Antique Blue Danube China Very Hard to Find Snack Plates - FOUR. Indentation for cup with tab on one side. Approx 8” x 8.25”. Could easily be used as additional salad plates as cup indention is slight. Last pic shows set -listed in groups. Pristine condition. I will consider all reasonable offers. NOTE: Blue Danube has a unique underglaze and is fired at an extremely high temperature making each piece dishwasher and microwave safe and very chip resistant. The individual casserole (like several other pieces) is even oven safe up to 500 degrees!!
