Set of 4 United Airlines First Class Casserole Dishes White Ceramic DC009R

Four United Airlines First Class casserole dishes, made by Watermark Products. See pics for stamps, they differ slightly - two say Watermark, two say Galileo Watermark. Otherwise as far as I can tell they're the same :-)  They have a textured waffle pattern under the rim for better grip by the flight attendants while serving. All four are in excellent condition with no chips, cracks, or heavy utensil marks. Great for airline collectors, or for serving small side dishes at home with an amusing backstory twist.  Fun fact: airline china is engineered to be incredibly durable to withstand high-heat industrial dishwashers and the rigors of flight, yet designed to be as light as possible to help the airline save on fuel costs.
