60's Brown/Grey/Orange/Beige Skeins Yarn - Tiffany Phentex -- Made in France

Lot of 6 "Pebble/Galet/Beige" Tiffany Phentex skeins of yarn. This yarn has multiple different tones of grey/mocha/orange and brown. Approximately 60 yards per skein, 3 ply "light bulking", hand wash cold water. Made in France of 34% viscose, 30% acrylic, 30% wool and 6% polyester. It feels so soft. I've tried to find the year of this type/brand of yarn and have been unsuccessful. My thoughts are that it's from the 70's, but I can't guarantee that. In excellent vintage shape, there are no flaws to note. Fuzzy, soft and cozy. Comes from a cat lover's home.
