On display at the Lynn Museum is a Diorama depicting 19th-century scenes of the Lynn, Boston, and Revere Railroad. And it is a masterful, miniaturized reproduction of the architecture, signage and scenery of the times. The Lynn-based artist Todd Gieg took twelve years to complete these first three, 4”x4” modules and hopes to complete the rest of the railroad Diorama within the next 8 years.
