Vintage 1974 Martex Provincial Roses retail Yellow King Sizd Sheet 4 piece set

Product Name: Vintage 1974 Martex Provincial Roses retail Yellow King Sizd Sheet 4 piece set
Includes 2 King pillow cases, 1 flat sheet, 1 fitted sheet. Good condition. The retail elastic on the fitted sheet has lost some of it's elasticity, but still works fine when I tried it out on a king size bed. I believe these are part of the No iron percale sheet line made from 50% combed cotton and 50% Dacron Polyester. Dacron is known for durability and quality. It's also hypoallergenic and mildew and wrinkle resistant.
