Silver Washed Fritillary Butterfly, 19th C. Watercolor

A couple more today from a group of beautifully executed 19th c. ink and watercolor butterflies, likely done by a young woman, 1870s or so I would guess, this one with the identification hand-written at lower left: Silver Washed. How to argue with the beauty and magical feeling-ness of a butterfly, and I love this one centered precisely on the white page, as if glimpsed mid air. 

9 1/4" x 7 1/4", very good condition.
