CafePress removes "Blue" products
CafePress has blocked the products based on Blue, and that shop has been closed pending whatever this is about. What their robots emailed me:

Let's see... there's nothing about "hard core" drugs, or drugs at all.
Although I did my best to make sure I used only public-domain images, there is a possibility that something I used was copyright, without my knowing it.
There certainly couldn't be anything in that patriotic, anti-tyranny content that anyone could find objectionable, except tyrants and haters.
So, must be the copyright.
