Artist Victor Henderson, a cofounder of the group, alleges that the mural, known as the "Brooks Avenue Painting," was improperly expunged last summer from its location using water blasting, according to papers filed this week in federal court.
The mural, which is famous for having served as a backdrop for a photographic portrait of the rock band the Doors, has been replaced with a replica of the original painted by another artist.
Ziman and his representatives did not immediately respond to a request for comment.
The lawsuit says that Henderson was not given the opportunity to discuss saving the mural. "Instead it is now gone forever and has been replaced by a replica that does not reflect the quality work" of the original artists, the complaint states.
Last year, The Times reported on the removal of the mural. Ziman had expressed a desire to paint members of the Doors into the replica but ultimately agreed not to do it.
The lawsuit argues that "Brooks Avenue Painting" could have been removed from the building "without substantial physical defacement, mutilation, alteration or destruction."
