help needed on three baseballs.......
 

The first two of these I'm unable to identify. Auto is a little light on the second - best pic I could get just now). The third - Robert De Niro - the signature looks so childishly constructed I'm almost embarrassed to ask if it's good :-) Wait. I've done much more embarrassing things...….so what do you think?

Second baseball is supposed to be Michael Jordan but there's no way (in my opinion) it's his autograph.

First one is Charles Johnson, catcher for the Florida Marlins, Dodgers, Orioles, Rockies, White Sox and Tampa Bay. He was also a member of the 1992 Olympic baseball team which was the first time baseball was an official Olympic sport.

Agreed. Like-Mike, but don’t think it was signed by His Airness.
