Vintage Red popular Wing 6 Cent Butter Crock Stoneware Advertising

This butter crock is very hard to find. It measures 4.5” tall x 2.75” tall. It has the 6 cent mark on each side. It looks to be faintly marked on the bottom popular but I cannot make it out. It does have a few chips and manufacturing flaws. Please see photos, you are buying as is. This piece is said to be a rare Red Wing find. A wonderful little piece to add to the collection.
