This beautiful monument is located at Bellefontanie Cemetery in St. Louis, MO. Wish I could have gotten better photos. She is quite beautiful but the glass and the sun were not cooperating with me.
She comes with an interesting story. According to A Journey through History Touring Bellefontaine Cemetery (a pamphlet I picked up at the front office of the cemetery):
During a trip to Italy in the early 1900's, Herman Luyties, owner of the first proprietary drug store in St. Louis, met a voluptuous model for an Italian sculptor. He fell in love with her and proposed, but she declined. Heartbroken, Luyties commissioned the sculptor to render a 12-foot marble statue of his beloved. The statue was shipped to St. Louis, where he kept it in the foyer of his Portland Place home. The several-ton statue was soon moved, because of its extreme weight, to the family burial plot in Bellefontaine Cemetery. When the weather began to deteriorate the marble he had her enclosed in the glass-fronted case. Luyties died at the age of 50 and was buried at the foot of "the girl in the shadow box".
