1 page, 5.25 x 3.5 inches, with the original hand-addressed envelope, Saturday evening, no date, circa 1880. Gracious handwritten dinner invitation, in full: "My dear Mr. Fish, If you have nothing better to do on Tuesday, will you give us the pleasure of your company at dinner, at six o'clock? Very truly yours, Geo. Bancroft." Tiny ink stain on the upper right corner; very faint staining, but still very good condition.
