This print is on thin paper glued to a loose sheet, but on the front it does say "Mode Z 1810" and "No. 7". The mystery deepens when we look at the outfits shown. I'm going to assume this is Mama, daughter and maybe the governess? (Her outfit is so much simpler...but I could be completely off base.) But Mama has a veil over her face. And her cape is pretty precarious. Also she looks like she's in danger of a wardrobe malfunction.
Her daughter has a simple gown with some sort of pantalets underneath. To bad we can't get a better look at her bonnet, she's dropped it.
Our governess is wearing a hat that almost looks like it could be a hair do. But I do like the little leaf shaped details on her jacket and cuffs.
Please click on these twice and really see the details in both the outfits and the drawings.
