Skippings Fine Arts has dated this piece to the 1850s.
Her portrait of the Princess Hosni Shah was exhibited in New York in 1853.

Her work remains highly acclaimed. Her pastel portrait of Aurore Demidoff and her son sold at Christie's for $10.000, and her portraits of the Saint Croix children fetched a similar amount at the same auction house.

The pastel presented here is drawn on size of the sheet of paper measuring 46 x 38 cm. Signed by the artist at the lower left, it is still sealed under its original glass with its original backing board. The framed size is just over 49 x 41 cm.
