I saw the number and the sticker which says nothing worthwhile,, If it was a serial number by a manufacturer,, it should be no problem to look up !! Let me know when you find it because I have looked at everything I can find online !! With the KIO with the number and with the sticker !! I have never known a serial number on pottery of any king except as stated earlier !! They use shape or mold numbers, decorators marks size numbers and some have pattern numbers !! Because the number is hand written I doubt its anything relevant to the figurine or it could be found !!
