The original version of this was created for author Audrey Niffenegger as a commission by a good friend of hers. It featured places from her novel Her Fearful Symmetry, which was set by the cemetery. There are a lot of crows in the map first draft, circling the area – and the gravestone which features a pelican feeding her young with her own body. I did a tour of the cemetery for background and research on a rainy day. It is a beautiful place.
