Rare Antique Butter Dish

Haven’t found another beautiful fine china like this!! Originally handcrafted 1970’s and in mint pristine condition. antique dealers were stumped and are looking into who the designer is. They believe it to be Franciscan, Herard Fritz& Floyd or Royal Daulton. They said a fair listing would be 250.00 on their auction site so I’m cutting that more than in half to sell. Thanks for looking and god bless!!
