This is an illustration for The Drabblecast that should be coming up in the next couple of days, for a story by Cat Rambo. (which you can now read here)
Here are some of the search terms I used on Google to gather reference for the story: milagros, porcelain doll parts, the Wailing Wall, Ankor Wat, artificial limbs.
I'm glad that Google exists and that my local library has an automated checkout system. It saves a lot of strange looks from librarians.
