Based on their crystal-clear images and reverse stampings/paper captions, two of these five photos appear to indicate Type I status (original negative from the time)...

4/21/50 Robinson Receives Silver Slugger Award from NL President Ford Frick: Acme Newspictures, 7-1/2" x 7", heavy crazing visible when angled under a light.

10/11/56 Robinson with Yogi Berra in the Yankee Dressing Room After Game 7 of the '56 World Series: Associated Press, 7x9, routine minor newsroom wear.

Then there is a Type III (duplicate negative or wire transmission from the time)...

1/14/50 Robinson at Hospital After Birth of Daughter Sharon: International News, 7x9, routine minor newsroom wear.

And the last two are likely Type III but do have some studio-quality Type I characteristics. Both measure 8x10 and have a reverse stamping for developer "Karl's Photo," with one being a sideline scene (featuring Sporting News writer J.G. Taylor Spink and Dodgers manager Burt Shotton) and the other a street-clothes barroom shot (with unidentified companions). Minor creasing throughout and perimeter mounting tape and corner tabs.
