Japanese mingei ware yunomi set

These yunomi are about 2.75" high x 2.5" diameter, "Made in Japan" stickers on the bottom of each cup. Made of brown/red clay. Based on the sticker, my guess is that these were made for both domestic sale and export. They are hand made and hand glazed/painted, each one a little bit different in size, shape and glaze. I chose the single cup pictured as it has the most variation in glaze and probably stood a chance of being discarded because of that but survived. Amazing to think that it probably took a potter a minute to make one and a painter a minute to decorate one and two unknown workers probably cranked out dozens of these in an hour and hundreds in a day. The definition of mingei ware. I found this set for $1.98 so couldn't pass it by. These may, at one time, have been associated with a teapot. Based on the fact that the label has survived on every cup, I don't think that these were used. Not calling these a mystery as they are meant to be anonymous in origin.
