Condition
Paper: Presents notably clean conditions in the central zone and the upper perimeter area. Oxidation is moderate, concentrating primarily in the lower-left corner and the lower-right margin.
Printing: The intaglio definition is magnificent. The burin work on Adams's stern features and characteristic baldness exhibits very high contrast, and the dense lines of the background shading within the oval are rendered with absolute sharpness.
Technical Description
Main Portrait: Adams is depicted in a three-quarter pose, facing to the right. The engraving accurately captures his mature physiognomy and the high collar of the period's civilian attire, based on an original drawing by the French painter S. E. Dubourjal.
Upper Iconography: Dominating the upper finial is a decorative pedestal supporting an inkwell with crossed quills and an unfurled scroll bearing the word "TREATY," a direct reference to his prolific and celebrated career as a diplomat and international negotiator.
Lower Vignette: The circular scene depicts a key historical event of his administration: the "Treaty with the Osages," signed in 1825. It portrays Adams—or his civilian representatives seated at a table, negotiating with Native American leaders of the Osage tribe in a frontier setting.
Signatures: At the lower extremities of the oval, the credits appear with complete clarity: on the left, the draftsman "Dubourjal," and on the right, the British engraver "T. W. Hunt" (Thomas William Hunt).
Editorial Reference: At the top, the heading reads: "HISTORIA DE LOS ESTADOS UNIDOS. P. 31" (History of the United States, p. 31).
