Chinese Qing Blue & White Dragon Jar & Cover Hand Painted

Chinese large blue and white hand painted dragon ginger jar. Really impressive size. Beautifully hand painted four clawed dragon, chasing a flaming pearl of wisdom. Interesting etched and inked signature to the shoulder, which I believe reads 'Yang'. Also there are double concentric circles to the base. Dates from the first half of the 19th century. Measures approx 24cm tall and approx 20cm diameter. No chips, cracks or restoration. Some firing marks to the body and wear to the foot, commensurate with age and use.
