In the Sopranos there was a painting of Tony Soprano with his horse Pie-O-My.
After Pie-O-My dies Tony ordered for the painting to be destroyed. Instead of destroying it Paulie Gaultieri keeps it on his wall in his house without telling Tony. He makes one change to the picture and has Tony's clothes changed from a suit to a generals uniform.
In a later episode Tony comes to Paulies house where he sees the picture. He gets angry and dumps it. While hes putting it in the dumpster he stares at the uniform and the sword.
What is the significance of the painting? Is Tony's reaction entirely down to his sadness of Pie-O-Mys death?
