Vintage 1980s Kitchen Towels Pair SouthWestern Designs New Linen Pastels

This is a never used pair of Southwestern-style towels made of linen. They've never been used! I saw a small spot on the back, and tried a Tide spot remover on it. I made it worse, but I'm relatively sure it would wash out. I'm afraid to try anything else!! Spot as shown in last photo. No tags on these, but I'm pretty sure they're linen. Still new and in "shape". Looks great from the front. 26" x 16" Features: • Southwestern landscape Size: 26" x 16" Condition: New Without Tags Spot as shown in last photo.
