Set of 2 Sioux Pottery signed High Elk Luta Sapa Color with Info Paper inside

2 beautiful little vases. Both are made by Sioux Pottery and Signed by Jeanne "High Elk". I believe one is the "Luta Sapa" color but it may be a member of the "Sitting Bull" color collection. The other vase is purple, blue and white. I am not an expert on those colors. The slate blue color bends into a purplish color . then pink, then, peach on one but no pink or peach on the other. I believe this is depicting a sunset. The figural carvings appear to be a range of mountains. The "fat belly" vase measures about 3-5/8 inches tall and is about 2-1/2 inches wide at the mouth with a slightly larger belly. The other measures 4-3/8" x 2-3/4" with a 1-1/4" mouth. There are no chips or cracks on either piece. The inside of the vase have a very nice shiny glaze. The paperwork was coiled nicely and placed inside the "fat Belly" vase. That is where I returned it to.

I recently found out that the Sioux Pottery and Crafts closed its doors in 2021. And from the Sioux Pottery Facebook Page came this:
"Sioux Pottery was sold in January of this year to Ryan Wilson of Great Plains Indian Trading from New Town North Dakota. We do not know what his plans are. (2021)

The last two phots shown are a photo of the "Sitting Bull" color collection and a photo of Jeanne High Elk herself working on pottery. Both of those photos are from the Sioux Pottery Facebook page./
