Ashton is working on a book called Tattoos for Two about tattoos with a shared meaning for two or more people. In her (his?) flickr group, there are lots of great photos of photos commemorating love, friendship, family, and departed loved ones. Thanks to Carl Zimmer for the heads-up.
These cute Brontosaurus buddies from eggandtoast‘s flickr photostream aren’t part of Ashton’s project (yet), but they should be!
I was well into reading some of the stories Ashton has collected before I remembered that my first tattoo is shared by 3 of my closest friends (one of these days I’ll post pictures and the whole story). In addition to the “shared experience” thing, it seems like “buddy tattoos” are a common way people get up the nerve to get a tattoo in the first place.
Shannon has posted lots of buddy tattoos on BMEzine’s ModBlog, as well (WARNING: some of these images may not be suitable for work!).
