Vintage HB Quimper shell butter dish

It certainly has some chips related to time on the edges but this old butter dish in the shape of a shell hb quimper, stamped and hand-painted decoration has the undeniable charm of beautiful old pieces. On an ivory background, a stylized flower decoration and a very shiny glaze. Model 289, initials r- u dates most certainly from the 40s/50s. Length 18 cms, width 10 cms, height 3 cms.
