Need help identifying minor league cards/photos

[KNH]

I have a thread on the memorabilia forum about a lot of minor league memorabilia which formerly belonged to Roy Mellinger who played for Cedar Rapids in the Central Association from 1914 to 1917. I thought I would put my latest post here also since there may be a lot of viewers here who can help and since this forum is for cards which might be what I have here. I'm not sure if these are baseball photos or baseball cards. They measure 3 1/2"x 2 1/2" and are about 1/16" thick. All 11 are from the 1914 Cedar Rapids,Iowa Rabbits roster. Their names are printed on the photos. Here is a list. Any thoughts on what they are or possible value? Thanks.
