Roger Guerin stamp marks identification

Hi.........I was hoping someone could provide more information on the black ink stamp "BFS" applied to the base of the Guerin vase.  Did he do work for department stores other retail outlets and this is representative of one of the outlets?  Any help would be appreciated!  Thanks

may we see the vase please?

Hi..........Sorry about that.  I should have added them at the start.  Both have floral overlay and are about 9" tall.  The overlay looks to be pewter since one of the stems moved very easily.  I have two almost matching vases.  Both are same stoneware design with some variation of the floral overlay.

Here are pictures of the one.





Any information would be appreciated as I haven't found much in the way of information on Guerin or the floral overlay designs.

Thanks!

I haven't seen that overlay on Guerin pottery before but there isn't much info available online at the moment

Actually their are 2 books with info about Guerin. 'Au gré du grès de l'art nouveau à l'art déco / Musée le Clockarium (French and Dutch) and the second book is 'Sel et feu' / Marianne Fauconnier, Jean-Claude Migeot (French). In the second book you can find some pictures from vases with pewter overlay. Not so many on the market because Guerin preferred the vases with wrought ironwerk.
