Cacti and Gaucho Sweater S-L

Would love to know the origin story behind this one! Funky cacti and classic Gaucho in a ready stance patterned sweater with v slouchy cut and lovely bateau neckline. The incredibly soft knit has the best ivy, rust and cornflower palette on a very light tan/off-white base. Has label "BZ Bee Original", handmade, circa 1970s.

• Size S-L (see measurements)
• Feels like alpaca..but we're not sure. It's incredibly soft and sturdy, nice quality
• Pulls on, slouchy with stretch
• Excellent condition, very light wear but no notable flaws

• Style No. T2090
