Art? No.
Heraldry? No.
Animal connection human? Yes
A well known phrase or saying? Um. I guess it is a well known phrase, but it is not an aphorism or anything of that kind.
Sch(r)ödinger's Cat? *opens box to check* No. *looks in box again* Wait. Why is there nothing but HOPE left inside?
Bigger than imaginary toaster? Well, it definitely could be very big. But it is really incommensurable with a toaster, imaginary or not.

Is it Lionheart or Heart of a Lion? playing my Wild-Guess card

And now some answers that I could have sworn I posted have disappeared; apologies again.

Human invention? More of a creation than an invention, but I will go with Yes.
Personal space? No.
Sense of humour? No.
Lions, Hearts? No.
To do with emotion? No.

Sorry, my German is pretty crap.

That's twice I have posted some answers from my phone and they haven't shown up. Not sure what is going on; sorry
Lebensraum? No.
Mankind? No.
Single word answer? No.
The act of being instantaneously incinerated? No.
Shipping Forecast? No.
Computer-related? Well, these days, pretty much everything is computer-related, and the AOTC is no exception. But since the AOTC also predates computers, I think the answer has to be No.

Pre-Renaissance? No. (I suppose there might have been some related concept prior to that time but the best answer is clearly No. Also, please don't now ask me a whole bunch of questions in an attempt to date the AOTC, since I am unable to give a clear answer. I can tell you that the google ngram viewer suggests that the phrase on the card seems to have started coming into significant use in the mid 1800s.)

Also, I guess I should clarify that the connection of the AOTC to computers is pretty tangential. I probably should just have said a simple No.

To do with economics? No. (Except very tangentially blahblahblah.)

Particular geographic location? Good question! In principle, no, and the AOTC has been relevant in various places in the past and in the present. But it's fair to say that, recently, it has a strong association with a particularly geographic location. So I'm going with Yes.

Hidden text

And what does recently mean, you might ask? Well, it means both in the last couple of decades and in the last year in particular.

Health-related? No.
To do with politics? Yes. *sustained applause*
Begins with P? I'll tell you for free that there are three words on the card and the first is the definite article. One of the others does begin with P.

Is the word which starts with a P "party"?

According to the MRLP, their moniker consists of three words.

P = Party? No.
MRLP? No.

Principle? No. Nor Principal, in case that was going to be the next question.

Lying Buffoon? No.
