It’s a convention in Germany to end letters and invitations with “Beste Grüße aus Berlin/ Rosenheim/Lieblos etc.
We don’t usually do this in English;

At the end of a letter

signature
name
name of place

is OK, I’d say

But, e.g. “Beste Grüße aus XXXX” at the end of an invitation to a trade fair sent to clients…

Just

Best regards

and ignore the reference to the place name?

or would possibly “from XXXX” make some think –“oh, that’s how they do it in Germany, it’s a pleasant little gesture”?

This crops up once in a while, any opinions on this?

Thanks
