It will soon be difficult to sell autographed slabs in California

David Siders reports for the Sacramento Bee that California Governor Jerry Brown has signed a law with a lot of new requirements for selling autographed items (such as books and coin slabs) in their state.

The bill was promoted by Assemblywoman Ling-Ling Chang, and Jedi Knight Luke Skywalker. The full text of the law is here and I could not understand it. I I have seen nothing about this law on numismatic trade web sites.
