Actually, that is a “Lawn Jockey.” They have an interesting history as they were used to show escaped slaves the route north. Different coloring told escapees how to travel safely, food and shelter available etc.
“Lawn Boy” is the kid that cuts your grass.
The jockeys was mostly called “black boys” by the generation that put them at the base of each of their driveways in, for example, Grosse Pointe, and thought they were adorable. When I did the web search, I used “lawn jockey”, but I’ve literally never heard them called that, ever (I’m in my late 50s, wow, how did that happen?).
The story about how they guided slaves also shows up in the “lawn jockey” search — it also took my be surprise at first, but a quick read showed me the unsurprising information that it’s not a true story. They were literally never used for that. The other story of origin is that George Washington commissioned a statue called “The Faithful Groomsman” as a memorial to Jocko Graves, supposedly a 12 year old son of a black volunteer for the Revolutionary army — Jocko froze to death on duty, you guessed it, holding a lantern.
