Glazed ware was usually marked on the bottom with a round ink stamp with the words "number red wing ware" circling inside a ring and with three numerals right in the center. It was this initial line of glazed ware along with several of the garden ware pieces embellished with the more intricate designs that formed the nucleus of what is now referred to as art pottery.

Apparently, this line appealed to the public. We know that sales of utilitarian ware were slowing at the time due to the combined effects of the Great Depression and the introduction of more modern ways of storing foodstuffs, typically, canning using glass jars. But the artware seemed to take off.

About this time, in the very early thirties, a man named George Djalma Rumrill appeared on the Red Wing Pottery scene. George Rumrill was strictly a salesman and he had founded Rumrill Potteries of Little Rock, Arkansas, as a company poised to sell art pottery. The details of the arrangement agreed to by George Rumrill and Red Wing Potteries, Inc., will probably forever remain unknown. We do know that Rumrill came in and took the existing line of glazed ware, expanded it, and started selling it throughout the county using the marketing organization he had created with his Rumrill Potteries Company.

Redwing, through Rumrill, reintroduced new shapes using old molds. New artware pieces were created and added to the line. The number of finishes offered was expanded and a line of "blended glazes" was introduced. Most importantly, Rumrill cleaverly catagorized the fledgling but growing line into sales groupings he called by creative names such as "Classic Group," the "Fern Group," and the "Fluted Group." Probably just as important, the wares no longer bore the name Red Wing; while they were produced at Red Wing, the wares were all labeled and sold as RumRill (sic) Pottery.

A new era in the marketing of Red Wing artware had been born. Sales increased. Lines were expanded and then expanded again. Twice a year new finishes were introduced.

Then around early 1938 the Red Wing/Rumrill relationship was disolved. The reasons for this have never been adequately researched. But Rumrill moved on to have his wares produced by other potteries, became ill and eventually died causing the failure of his business.

Red Wing Potteries, on the other hand, continued production of the artware line, which it sold as Red Wing pottery from 1938 on.
