PostSecret - Viral ad for new Franz Ferdinand album?

I saw this on PostSecret today, and wondered if it was made by some ad agency pimping the new album recently released by Franz Ferdinand? Notice how prominent the name of the band, album title, and release date are. The 'postcard' was placed on the PostSecret site today, so I'm assuming that whoever made the postcard made it either before or around the album's street date. Maybe it is a coincidence, but I would think that it would be a great bit of viral marketing, considering the popularity of PostSecret.

From the band's website:

Our second album is released worldwide in the first week of October on Domino (UK) / Sony (RoW) on multiple formats, so look out for bonus features.
