Vintage Porcelain Cigarette Box C. 1920's

This is a pretty vintage cigarette box shaped like a book. It has lots of gold trim, purple floral with green vines. It has a mark on the back but I have been unable to identify it. It is a crown sitting on a heart shaped figure. In the crown there are three stick figures. Under the mark are the words "Royal Europe" in small print it says "piente a la imain" If you know this mark and can help me out, I would appreciate it! I looked in many different reference places and asked a certified antique dealer. This box is in great condition with very little wear. This item will ship priority USPS mail for 4.60 in the US.
