The second class, from 6:30 to 8:30, is for adults, and artist Mark Spangenberg will join Momii to discuss the similarities and differences between abstract and realistic art. Each class is $5 and space is limited. To reserve your spot, call Ed Keesling at 760-365-8193. The art gallery is located on Cottonwood Drive in Twentynine Palms.
