When we say large, we're talking large. It's really big.
The crop c**k - let's hope it wasn't made by aliens, right? - took the officers 'completely by surprise' - whilst they were out hunting down a person wanted for questioning in West Cornwall.
I mean, look at it.
The Devon and Cornwall Police drone team wrote: "It's absolutely amazing what you see from the air and sometimes we're caught a bit off guard.
"Whilst in West Cornwall and searching for an offender who'd recently run off from police, we came across this unusual piece of artwork in a field, taking us completely by surprise."
Various jokers on social media have been positing their theories as to how the field wang got there. One suggested that it was 'an arrow' to tell the police that the wanted man went over that way.
Unlikely, that would take some almost mystical forethought.
Over on Facebook, one person said: "The best thing is that someone hasn't just done it randomly they have actively planned this, procured a grass cutting apparatus, then made there [sic] way to this field and gave a circumcision if you will."
However, the best joke we've spotted so far was from one wag who suggested that the alleged offender must be a 'hardened criminal'.
Excellent work, there.
This isn't the first time something like this has come to our attention.
In fact, when President Donald Trump visited the UK last year, there was an unusually phallic welcome symbol moved into a field for him underneath the Stansted Airport flight path.
It was a gigantic willy, and underneath it said: "OI TRUMP"
As if they'd need words to get his attention after that.
It's not clear whether The Donald saw it or not, but let's hope that he did.
This particular artwork was the work of an eco-friendly online marketplace called Born Eco. They said: "Guess who's been busy today mowing a stiff message for Trump under the Stansted flightpath... Please share and let's see how far we can spread the welcome!"
In another field, they did stick a polar bear with the slogan "CLIMATE CHANGE IS REAL", too. So, it's not all willy jokes.
It's mostly willy jokes though, and that's a good thing.
