Touching Up a Masterpiece

This guy said he was hired to touch up this artwork on Ward Parkway. He said he can tell that it's actually 3 different pieces - the top, the side columns and the frieze (center piece). They are marble and were brought in by JC Nichols from Italy, and not artistically cemented together. He said the main piece looks like something created for a marriage with the two family crests but he hasn't been able to find either crest. He is also adding an anti-graffiti paint to prevent vandalism.
