Vintage Robinson Ransbottom Blue Spongeware 1 pt. Low Jar, excellent condition!

Just a unique piece of Ohio history. 1 Pt low crock jar from Robinson Ransbottom potteries in Roseville, Ohio. It is vintage. It does have crazing on the outside. Every spongeware item I have seen has this crazing in the glaze. It is not crazed on the inside. No cracks, chips, or signs of use. Marked on the bottom.
