Robinson Ransbottom Pottery Crock High Jar R.R.P. Co from Roseville, Ohio

Pre-owned See pics for condition Pics show a possible fracture in the glaze of the pottery, or hairline crack??..(see to the right of the tree that is to the left of the house). I cannot feel this line with my finger. This line is also seen inside the pottery but is also not felt. Was very difficult to catch this in my photos. Approx 5.25" in height 1 qt.
