Marin photographer Glen Graves is seeking at least 30 women age 40 and up to participate in his art project, “Women of Spirit,” which he started 12 years ago. He is also seeking venues to hang and exhibit the project. The series of nude photographs is an attempt by Mr. Graves to question modern concepts of beauty, and there is no deadline for participation. Call (415) 450.1079 or email email@example.com for more information or to participate. Mr. Graves will have a digital presentation and discussion of the project at the ARTrageous Gallery on April 5 in Old Town Novato, from 5 to 9 p.m.
