We can certainly agree on that. The article didn't mention whether there were other covers of magazines that he was on with real headlines and these were mixed in. That would make this more believable to me.
Honestly it's small potatos but given that in multiple televised interviews and at least one in print he has pointed to a framed photo of his inauguration and repeated the false claim that it was the most well attended in history I wouldn't put any exaggeration of his greatness past him.
And it all keeps your tiny mind occupied...a valuable public service.
