4 Rare French Blue Stoneware 9.25” Plates Raised White Anchors Pottery Ceramic France

This listing is for 4 unusual (rare?) stoneware plates made in France. They have raised white anchors on the plate surfaces.

Stamped "Made in France". They are in overall good preowned condition with no significant chips or cracks. There are some minor pinpricks and nicks to the anchors and plate edges revealing the reddish colored stoneware under the glaze. Please see pics.

Some expected use scratches and wear to the surfaces as well. There is also crazing to the cobalt and white glazes which shows with a whitish-hue in some areas. 9.25” diameter.

I searched far and wide on the internet and couldn't find any other examples so can't say much more about these other than I assume they must be fairly uncommon and hard-to-find. 

They will weigh about 5-6 lbs packed safely. Thank you!
