An extraordinary quarter plate relievo ambrotype of a man strikingly posed in partial Masonic regalia—wearing an ornate Masonic apron while topless, without a shirt. His bold expression, combined with the detailed symbolism of the apron, including the square and compass, lends a rare and unconventional quality to this ceremonial portrait. The subject’s fur hat and sash add to the dramatic presentation, making this a highly unusual and visually arresting piece.
