Watercolor of a Swallowtail Butterfly
This Swallowtail Butterfly is resting at the top center (well, almost) of an oval frame.
Remove the frame, recenter the butterfly, or use it as it is and add more butterflies.
The download from NGA is a high resolution image so you can even
just use the butterfly in other projects.
