Chicago Cubs negatives and photos 1945 WS
 

I have an opportunity to buy a negative of an aerial photo of Wrigley Field from 1945 as well as negatives of Chicago Cubs team pictures of 1929, 1932 and 1938. The negatives and photos were in a lot purchased in an estate sale from a Chicago Cubs team photographer. I am working at finding out who the photographer was and to look at the negatives and prints for myself. There are 600+ pictures and negatives from 1960-1980 of the Chicago Cubs. I am wondering if someone could give me an idea of the value of such negatives. Thanks
