My guess, and it’s just a super sorta random guess, is that an illustrator who lives in your village/town/city made an ABC book/card/poster of the various highlights of your area.
You know, something recognizable for each letter of the alphabet.
Sensibly, you really really must help your kids do the same, yes?
Arm them with cameras, an ABC list, and some snacks to munch on while they work.
When each letter has been represented, choose the favorites, and make an ABC book/card/poster.
And then what?
Make copies and hand them to guests who visit over the next few weeks. On those days when you furiously want 10 minutes to yourself, make your guests go out to find and photograph themselves next to at least 10 of the highlights before they can come back.
That oughta do it.
