7-gatsu 7-ka PV?

[Sai]

This struck me as kind of odd... In one of the pics posted in the Nana Picture a Day thread, which had chibi versions of (I think) all of Nana's PV costumes, there was one near the end labeled ' 7月7日'.

So my question is... Did 7-gatsu have a PV that somehow I never stumbled upon? What was it on, if such a thing exists? :nin

Edit: This is the picture I was referring to.

Thank you! It's really simple and beautiful, but sometimes that's best. I'm glad this exists, at any rate.
