Postcard 1907 University of Minnesota Football Players Northrop Field

I am going through boxes of Minnesota postcards I purchased a couple of months ago.

 
This is a great 1907 post card of Northrop Field University of Minnesota with football players on the field.
Will be listing on an eBay auction tonight. Wonder what else I will find in these boxes of over 2000 postcards.
I think this one is extra special not only for the university fan but for any one with interest in genealogy that had family going to school that year.
