Vintage 1950's Rooster Linen Stemware Coaster Slippers (Set of 12)

Vintage 1950's Rooster Linen Stemware Coaster Slippers (Set of 12) White Linen with Silvery Light Blue Embroidery and Trim 12 Coasters measuring approximately 3" x 3" Coasters have some stains, light spotting, and some discoloration. I did not attempt to remove as I was unsure of what would be the best way to do so and did not want to ruin them. Overall in excellent condition except the stains. No tears, frays, holes, or signs of wear. Please feel free to ask any questions.
