JUST WANTED TO SHOW OFF CHAGALL PAINTING FOUND IN THRIFT STORE + GET HELP w/SIGNATURE ON 2nd ONE

Found these today at a local thrift store! The one is signed Chagall & it's actually not that far off (photo after signature is copy of original), is it?
And any help with the signature on the 2nd one would be appreciated.
Thank you!

 

First one is almost certainly from one of the chinese art factories done on a production line. https://www.instapainting.com/blog/the-secret-lives-of-china-art-factory-workers "Legend still has it that Huang once produced 50,000 paintings in a month and a half for Wal-Mart, the US retail giant". Supposedly Trump is a big fan of this chinese reproduction art, so there must be a market for it. You know how to contact him on Pennsylvania Ave - https://nypost.com/2017/10/20/trumps-renoir-painting-is-a-fake-museum/ President Trump insists he owns a real Renoir painting — but a Chicago museum says the version he has isn’t the real deal "President Trump insists he owns a real Renoir painting — but a Chicago museum says the version he has isn’t the real deal"

Name on the second looks like M Dunoseau?

 

Yep first is a reproduction still nice though. Second appears to be dunoseau or dunaseau.

 

Also in your first painting look at the bed and the blanket on the wall to the side of the bed compared to the original chagall. There are differences here and there.

 

the 2nd looks like Shona carvings...so I'd look towards african...

 

Blanket on wall could be from a different angle but same blanket (along edge) - the bed is absolutely different; good eye!
