I haven't posted in a while, but wanted to share this very cool Sugar Ray Robinson card.
I believe this set was issued by the weekly British publication Boxing News. The image was also used for one of Robinson's Exhibit cards that @Curt_Burner shared. It's the same size as the Exhibit cards, but the card stock is thinner.
Robinson is listed as the welterweight champion, so I'm guessing this card was released at some point between 1946-1951.
