A good choice for this is anything to do with penguins, obviously. Last year in particular must have been the Year of the Penguin. I had several to choose from that I really loved.
This year: no penguin cards at CVS. No penguin cards at several grocery stores. No penguin cards anywhere else I went in the last two weeks. Tonight, at Hallmark, I found one penguin card. It had very twee cartoon penguins on a lime green background, and a Bible verse in the inside text.
I'll be going with something else, thanks.
