Where do আপনি think England has his tattoo?

It`s not something canon, it`s only implied from a sentence in his version of Marukaite Chikyuu "My tattoo really hurts, but it's a hot six-string!"

If this is canon অথবা not, where do আপনি think it is. In the early episodes of হেটালিয়া we have seen him undressed frontal and sideways.

I have not seen his backside bare so I believe this tattoo is on his back, all over his back অথবা on his shoulder blade.
