State Box

[davg2000]

For what it's worth, ALPM has Lincoln and Mary in their accepted places, but Clara Harris is seated close to the box's rail at the viewer's very left. Major Rathbone, in uniform, is seated behind Clara and to her left. Although you can't see down into the box, it certainly appears to me that both Clara and Henry are seated on chairs. There is no settee. (But that surely appears to be a settee in the picture posted by RobertLC.)
