Except the parlor, perhaps? Well, it’s identified on the back as the boudoir, but the meaning of words changes according to time, place, and whim, so we’ll accept her terms. This is a charming stereoview image of two circa 1860s ladies in full dinner dress, sitting down to play with their new sewing machine.
I can’t identify the machine, but I see the seamstress has a music stand and harp close to hand, just in case she wearies of needlework. And a friend with a manual close by to instruct and advise. (Ok, it’s not a manual – what could it be?) A picture-perfect postprandial occupation while the gentlemen are smoking: a lamp, vases of flowers, elegant furnishings, and a congenial companion – what more could you ask?
