It’s a busy day in May at the Museum of Fine Arts when a small group meets by “Eternal Presence,” a bronze model by Boston artist John Wilson. Around a dozen people are there for an unofficial tour of the MFA, led by organizers from local non-profit Design Studio for Social Intervention, or DS4SI. Lori Lobenstein, DS4SI program director, co-led the tour. She pointed out the location of the model of "Eternal Presence," which stands in a corner by the staircase in the courtyard.
