Hi all,I found a few bits this morning at sparrows and this little jar is the only one I'm not sure about,6cm ht,the rim 6.5 to outside,it has three seams and a sort of flower pontil,dragging your nail around the outside of the foot You can feel wear,the rim looks worked,I hope you can see from the pictures,it's a sort of turquoise blue,so a lovely piece of medical history or a ghastly piece of Mexican tat?many thanks.
