Antique Ironstone China Question - J.M. & Co. Bowl

by Sally

Antique Ironstone China Question - J.M. & Co. Bowl:- I recently purchased a huge SOUP bowl with lid that has the pottery mark of Lion and Unicorn with Ironstone China under the lion and unicorn. Under the IRONSTONE CHINA is J.M. & Co.. Now, I have recently learned from your site that after 1890, the country of origin must be listed on the ware. There is not a country listed, Just the mark I have described above! My question are do you know any information as to the date of this item and any information on J.M. & Co.? I can't seem to find any information on the maker. This would be greatly appreciated!

Thanks again,
Sally

I have a few more details that I thought you might need since I can't get a great picture of the mark! The mark is BLACK, not blue. The lion and Unicorn are sitting down, not standing like in some marks I have seen! Can't make out any initials in the middle of the lion and unicorn. Under the Lion and Unicorn, are the words: IRONSTONE CHINA, underneath that is J.M.& Co.. I hope this helps you find info for me as to the approx. date and infor on J.M.& Co.
