Lot of 2 satin vintage pillowcases standard size silky soft

The aqua one is labeled scent – Sation. there is some discoloration that has no explanation because it was never used or washed. My guess is that it was in storage so long sometimes elements in the air can cause a Fabric to have slight discoloration but it’s not a stain. The cream colored pillowcase is also standard size very lustrous vintage satin probably from the 1940s very well-made. No labels . Both are wrinkled from storage.
