Muralist Saul Levine may be a victim of a second artist named Saul Levine, as far as web-based research goes. A web search on “Saul Levine” returns several results for a controversial film maker and professor and little to nothing about the post office muralist, who also seems to have made a career of illustrating covers for pulp fiction books.
Levine created two post office murals: Ipswich Tax Resistance (Ipswitch, Massachusetts) and Composite View of South Hadley (South Hadley, Massachusetts).
