It's possible you're thinking of:
* A misspelling: Perhaps the artist's name is something similar, like "Hopkins" or "Hobbins."
* An artist you've seen but don't know the name of: Could you provide more information about the artist's style, the type of clowns they paint, or where you saw their work?
* A local or lesser-known artist: If the artist is not famous, they might not have a wide online presence.
To help me find the artist you're looking for, please provide more details.
