Engraving depicting a packed political assembly identified in the image as a Union meeting, showing a dramatic interior view of a theater filled with spectators, banners, and speakers on stage. The composition captures the energy of a large public gathering and features finely rendered architectural detail, including tiered balconies, columns, drapery, and an ornate domed ceiling. Visible printed text along the sheet references Harper's Weekly and December 19, 1859, adding period context to the scene. This historical print would appeal to collectors of Civil War era imagery, political Americana, and 19th century illustrated journalism. The sheet appears to be presented loose in a protective plastic sleeve, with full margins visible. The imagery and publication line make it a strong decorative and documentary piece for framing or archival collection. Size: approximately 22" H.
