Viewers stampeded the Denver Art Museum this past fall and winter to take in the traveling blockbuster El Greco to Picasso From the Phillips Collection. The show was such a big hit that tickets for the last couple weeks sold out in advance. It's no mystery why: The artists are so famous that virtually everyone's heard of them. Along with stunning pictures by El Greco and Picasso, there were gorgeous works by Ingres, Cézanne, Renoir, Braque and Kandinsky, among others. The DAM has apparently figured out that bringing in the big names is what's sure to bring in the big crowds.
