There is an almost identical jar and cover in the Rijksmuseum, Amsterdam, museum number AK-NM-6439-B. This jar is illustrated in Christiaan Jorg, Chinese ceramics in the collection of the Rijksmuseum, Amsterdam: the Ming and Qing dynasties, p.174, pl.194, where the author notes the rarity of this form.
There is a jar and cover of the same ribbed form in the collection of the Victoria and Albert Museum, London, museum number C.17&A-1958. Theirs has silver mounts, and the decoration differs, however the floral decoration is reserved against a coloured ground in a similar way to ours.
