Here is a group of five brown porcelain single grooves of a similar style. I noted that these all have somewhat different glaze colors. These brown LRIs add some zing to the usual white porcelain LRIs that are readily available. There were quite a few white LRIs for sale at the recent Mid-Ohio show in Springfield, Ohio. This style is quite unique to porcelain LRIs, as there are no known glass equivalents. Enjoy!
