I received this odd little gem via Postcrossing recently. The sender noted I liked both bats and cats - and oh, I do! I do! - and that I might be especially fond of them in combination. Indeed! This was RU-2324265 from Russia. Granted, they're not real cats or real bats, but I like the fanciful intersection of photography, craft, and illustration. And what's with the hands? I don't know, but I think they're kind of creepy cool.
This is why I keep on Postcrossing year after year (I've been Postcrossing for more than 7 years now) - all these fantastic little surprises in my mailbox.
