Vintage turtleneck pattern wool sweater

Vintage sweater, unfortunately no tag so it could be homemade. Does not identify brand, material or size. It definitely feels like a wool/wool blend. Many vintage patterned sweaters use this, and it gives warmth and a slightly fuzzy texture. The bold geometric / southwestern / Aztec-inspired motifs are very characteristic of fashion from the 1980s–early 1990s. These designs were popular in knitwear then. Very good condition. No holes. Minimal pilling. Selling as is due to no tags. Looks to be a size medium based on measurements
