Vintage Blue Southwest Print Sweater

100% Cotton sweater with a lovely vibrant blue southwest print. I purchased it 10 years ago in a second hand shop in Denver. I can't find anything about the brand, but I believe it dates from circa 2000. It is sewn with the seams exposed on the outside, so I always thought it could be easily reversable if you took the tags out carefully, but then, alas the inside got a stain from washing with something -shown in the last photo. This does not show on the outside at all.
