1964 John F. Kennedy commemorative with FDC cancellation, "First Day of Issue," postmarked "Boston - May 29, 1964 - Mass." Also affixed is the 1961 Worker's Compensation Law commemorative. The stamps and cancellation are on a large photographic print of Kennedy standing with members of his cabinet at the time that the Worker's Compensation Law commemorative was issued. My scan cut off the lower edges, but they are in very good condition, as is this image, the postmarks, and the stamps.A great association. his letter comes from the estate of Justice Arthur J. Goldberg, who was Secretary of Labor at the time that Worker's Compensation Law was passed, and who is pictured next to President Kennedy in the picture. This lot will be accompanied by cast iron provenance and a COA written on an original sheet of Justice Goldberg's Supreme Court letterhead. Justice Goldberg was a luminary of 20th century American politics, a patriot, and a stalwart of organized labor. He had earlier served in the Office of Strategic Services (OSS), and was later General Counsel to the CIO. His success in this capacity led him to be appointed as the Secretary of Labor by President John F. Kennedy, and subsequently, as an Associate Justice of the United States Supreme Court. With considerable misgivings, he left the Court at Johnsonâe(tm)s request to become the US Representative at the United Nations. He resigned from this position after disagreements with Johnson over the conduct of the Vietnam War. Justice Goldberg was a giant of the Democratic Party in the 1960s. A great piece of Americana that will make an excellent addition to any collection about American politics, political history, trade unions and organized labor, philately, the Cold War era, or Washington D.C.
