OLD DISPLAY CASE?

APPEARS TO BE WOOD AND PLASTER. SEEMS VERY OLD.I SEE 3 COASTS OF PAINT FOR SURE. IT IS 9 INCH SQ. BUT AT ITS PEAK IT IS 21 INCHES. DOES THIS STYLE HAVE A NAME AND PURPOSE? ALL THAT I KNOW ABOUT IT IN THE SENSE OF MEANING, IS A VERY VERY WEALTHY MAN HAD IT AND SAVED IT FOR A REASON, NOT SURE IF TOTALLY SENTIMENTAL OR NOT?THANKS
