The Newbie is rolling briefly out of hibernation to take a best guess at the answer: Hearts Challenger, also known as Hearts Revolution. It's not entirely clear what Hearts Challenger/Revolution is all into (music? ice cream? t-shirts? organized rebellions?) other than hanging these bears, but evidence is mounting:
- Their zine links to a Tumblr page with dozens of hanging bear photos
- According to a bio, their name comes from a song by a UK an English riot grrrl band named Huggy Bear
- Their Twitter followers say things like, "I see your bears everywhere!"
- Their ice cream truck, which seems to have a home in the Franklin Hills, has similarly fluffy and pink-masked adornments
And finally, in response to a direct Twitter question from yours truly, the response came simply with a link to the bear photo Tumblr.
Case closed? Or hung jury?
