Thanks, Bailey, for finding this out:
http://www.loc.gov/exhibits/cwaj/online/index.html : a Library of Congress exhibit, the Miura is there too. The work’s name is Blow. The exhibition was April-June 2007. The artists are from the College Women’s Association of Japan (http://www.cwaj.org/), which appears to have an exhibit every year in Tokyo. The artists are not all women.
That’s all I could find. The internet’s most popular person, as I’m sure you saw, is Yuki Nakano (http://yukister.com) but that’s pretty different. :/
Mystery solved. :)
