This piece derives from the Stolk collection, a nice Dutch collection of early Chinese ceramics. The auction catalogue description was; Chinese Cizhou earthenware pot with two ears and linear decor in brown glaze over white slib with transparant overglaze, likely Jin/Yuan dynasty, provenance: Collectie Stolk, 9 x 12 cm

The dating is probably somewhat later, like Yuan / Ming; 14th century. Compare to acc. nr. 582-D4 from the National Gallery of Victoria; dated 14th century. Or from the Mak Frankfurt , OR 1027, dated Yuan.
