Extremely desirable envelope panel addressed entirely in the hand of George Washington, 6.25 x 3, no date but circa 1776, in full: "To the Hon. Ab'm Yates Esq'r, Presid't of the Congress of the State of New York." Affixed to a slightly larger sheet which bears a notation on the reverse by autograph dealer Walter R. Benjamin certifying the authenticity of the piece. In fine condition. Encapsulated in a PSA/DNA authentication holder. Accompanied by an engraved portrait with facsimile signature and a one-page ALS from Abraham Yates, signed “Abm. Yates, Jr.,” June 1, 1788, which contains “notes that I made this morning in Congress.” Abraham Yates became president of the New York Congress on August 28, 1776, and served in that role for only a month, presumably dating this piece to that historic year.
