@ragberk,
I was given it by a long time friend who knew I am rather keen re Italy. (I'm irish american but have been interested in piazza history). Where she got it (them, actually, as there are more magnets), I don't know. I might make a guess, that in her volunteering at gift shops, she saw them and picked them up.
I'd just mail it to you as a present. since I got it as a present, but that would be quite abrupt. Plus mailing a magnet might be tricky.
On that, see if you can get your email off of the post - ask the mods via Contact Us, if I haven't warned you fast enough. Such links famously collect spammers.
