BOWDOIN COLLEGE ARTIST LUCY WALKER, foreground, attends a reception for the unveiling of “Maine Street, Brunswick” — a large mural depicting downtown Brunswick — at the Mid Coast Primary Care & Walk-in Clinic Saturday at Brunswick Station. The 14-foot-wide oil-on-linen mural took two-and-a-half years to complete, and began as a project in Bowdoin College art professor Mark Wethli’s Public Art class, Walker said.
