Residents who noticed the familiar “bee” missing from its perch atop the Council on Aging building need not fear that it has flown away. Town workers recently removed the 4-foot-long bee scuplture so that it could undergo a much-needed restoration. Dave Litchfield, of Litchfield’s Art & Sign, is carrying out the work, which is expected to take several weeks. The bee was created in 1975 by Richard Edlund, a corporate designer, to mark the 100th anniversary of the founding of the first public library in Pembroke, Edlund said last week. At that time, the building was the town library. Edlund’s late wife, Lucia Millet Edlund, is a former head librarian. In the library’s early days, Edlund said, the Pembroke Ladies Reading Society held spelling bees to raise funds. Edlund said he made repairs to the bee in 1979 after it was stolen and recovered, and that he touched it up periodically over the years. The latest renovations will use a more durable protective material so the scuplture will last longer, Litchfield said in an interview.
