This is an excellent original antique (mid to late 19th century) 4 gallon stoneware crock with salt glaze on the exterior and Albany slip glaze on the interior and a cobalt blue flower decoration on the front. It is unmarked and I don't know for sure who the maker is, but the cobalt decoration is very similar to one I found online attributed to Gommel and Forster of New Ulm Pottery in Minnesota. New Ulm Pottery crocks are difficult to find.
If you think it was made somewhere else, I would love to hear from you! The crock is in excellent original condition. There are no chips, cracks, hairlines, repairs, or flea bites anywhere. There are a few spots of sticky residue as if it was on display in a kitchen somewhere, but I have not cleaned it and it is pretty clean overall.
