Boxing pick-up
 

I just picked up this double sided picture(photo) of the 1921 Dempsey / Carpentier fight in Jersey city.If you take notice that on the top of the picture it say plate I and on the other it say plate II .
I was told and likely a wrong statement that these were the pictures used to make magazines. I do see that it also says Photograph, International Newsreel under the pictures.Kind of neat.
Does anyone know what they really are and if it has any value. Thanks.
