Hard to ask when you don't know the terms. Little round pictures in maps.

[BordersoftheRealm]

Hi, all.

Please bear with me. Though I like drawing maps, I am not a trained cartographer. But I do have a question, and it's hard to ask when you don't know the vocabulary.

Say you've got a map of a city, like an old map of London. And around the border of the map, you have little round or square windows or medallions with pictures of some highlights of the city, say Tower Bridge or The Crystal Palace.

What kind of map is that? Is there even a term for that? And what are those little pictures called?

Basically, if I wanted to do a Google image search to see examples for inspiration or style cues, what terms should I be using?

"map with little pictures on it" didn't yield any results, you know what I mean?

Thanks in advance.
