VTG Sweater Cardigan Fair Isle Hand Knit

I have listed this as a small but there is no size as I am quite certain it is hand knit. I also know that it is vintage because I have owned it for over 20 years. Approx 20” armpit to armpit, 21” long. The stitching on one seam is slightly looser than the other but it is still secure unless it’s really tight on you (last photo). Good vintage condition, no major flaws.

This item is sold from a vintage boutique in Las Vegas, NV.
