artwork by Peter Arno: No signature is it authentic?

From auction a few hours ago. This water color by Peter Arno does it look authenticate? The American Antique Auctions in Haddonfield nJ listed a whole series of these like 10 or 12 as by Peter Arno. There is no signature or any other indicia. Nor do they show the backs of them. Shouldnt they have said "attributed?"

EDIT: to correct the auction house.

 

Doesn't particularly much like Peter Arno's later work, does it? Would/could you post a link to the auction.

Reminds me of this

 

Perhaps they had an impeccable provenance.

perhaps but nothing of the sort is mentioned there. is it not customary to say attributed to when lacking a signature?

 

Google search comes up with name Burr Schafer Original Cartoon, New Yorker Magazine but unable to find that particular sketch.
