From 10am to 1pm on Sundays, admission is free at the Philadelphia Museum of Art. This saves everyone a cool $8 a ticket. Pretty much all of the exhibits are open for viewing by everyone, but special exhibits may still cost you $$$ for admission.
You'll find everything from local artists (Andrew Wyeth being one of the most notable) to Van Gogh and Picasso, among the many, many rooms of the Museum. My favorite is the Far East Ancient Art Exhibit.
