Some nice Bob Ross attempts.

Indeed, any of say Ludwig Kirchner paintings could've been added to this collection, and no one would spot a difference without being previously acquainted with his work and fame.

Some of it looks not unlike Rosseau, which is quite highly regarded, despite many considering them a joke at the time.

Use just ugly for that case.

After all, art may only be a matter of consensus.
