Funny how Jackie Robinson isn't shown in a Brooklyn Dodgers uniform. I'm guessing the picture was taken when he was a minor leaguer in Montreal in 1946 and airbrushed.
This Jackie Robinson card is from the Exhibit set. It was issued over a long period (1947-'66) and was essentially a set that changed its players over the years but kept the same design. I have written a page on my Web site about these:
The card looks legitimate, but take care because it's known to have been reprinted. Also, set chasers need to be aware that most cards are fairly easy to get, but there are about 20-30 cards that will be quite difficult to get, since they were only issued for a year or two.
