3 3/8" PLATE VASELINE(?) NICE COLOR GOOD CONDITION HELP

I WANT TO TELL YOU UPFRONT THAT I DONT KNOW ANYTHING ABOUT THIS PIECE EXCEPT IS IS QUITE LOVELY. I BOUGHT IT THIS MORNING AT AN ESTATE SALE IN THE CENTRAL TEXAS FARMING TOWN OF FRANKLIN, TEXAS. THE DESIGN IS VERY NICE AND THE COLOR LOOKS TO ME LIKE VASELINE GLASS. THE PLATE, OR DISH. IS 3 3/8" ACROSS. tHE CENTER HAS TWO HEARTS AND ARROWS AND AROUND THE EDGE ARE HARPS. VERY ATTRACTIVE.
