General Jean-Victor Moreau (1763-1813) Francois Pascal Simon Gerard (1770-1837)

The picture has something of this: people, wear, man, lithograph, sword, woman, music, veil, portrait, paintbrush, retro, two, vintage.
Perhaps it’s a painting of a man in a blue uniform with a red hat and a red scarf around his neck, standing in a field with a tent in the background.
