For the past 14 years, the Mattie Rhodes gallery on the Westside has commemorated the Day of the Dead by asking local artists and community members to make altars in memory of ancestors and loved ones who've passed away. But this year, the Nelson-Atkins Museum of Art is collaborating with the Mattie Rhodes Center, as well as the Guadalupe Center and the Mexican Consulate, to create a large community altar in the museum's central Kirkwood Hall.
