anatomy of flight

I found these a few weeks ago in the Castle Drogo shop and after buying two for some small friends, I ended up buying six for me because I couldn't decide which ones were best. They reminded me that after In Absentia I wanted to make paper bird beaks to stop people from talking. They also employ colour very creatively, which I probably wouldn't have: I always imagined they'd be made with a good, sharp HB pencil.
