Yes, I have 2 of these items. If you notice, I sent a pic of the bottom of each so you can see the stamp.
Dimensions are
11-1/2” Tall
7-1/2” Wide @ Center
8” wide at handles

Apologies for not catching that.
The marks on your pieces were ones Ginori used in the 18th and early 19th century; these are in the Moorish taste and were probably used for wine or oil (they would have had a stopper, now long-since lost).
Because of Ginori's lengthy production, there are a LOT of things made by him on the market; the danger - if you are thinking of selling these - would be to over-valuing these.
Based on the photos and information provided and subject to examination, this is:

A pair of tin-glazed earthenware wine or oil vessels
made and marked by Richard Ginori, Italy, 18th or early 19th century
In the Moorish taste, with two shaped handles, both marked underneath.
11 1/2 inches tall; width across handles 8 inches
$3,000-5,000*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you for using Mearto.

Is this appraisal for 1 item or for the set of 2 that I have ?

It is for the pair

Can you find me a buyer, or where would be the best place for me to sell these items? Please and thank you

We work with lots of auctioneers from relevant and highly qualified auction houses, not only in the US but around the world. Your item is in our database of leads and interested auctioneers will reach out to you directly on your email if they can help you sell your item.
