These molded, decorated pitchers were popular from about 1830 through early 1900's. Midway through there or about 1870 would be considered there largest productions. Many, many potteries (mostly eastern US) made stoneware bowls, crocks, pitchers, etc. Without specific markings its pret-near impossible to determine a 'maker'. Yours appears to be in nice condition, no cracks/chips. The grazing is acceptable and I really like the blue/green color. A nice pitcher indeed.
