RhysIt is from the 1870's and most likely the early to mid 1870's. My guess would be 1874 give or take a year or two.
It is a College Team. I have yet to see a non-college team to pose in front of a building like this but I have literally seen hundreds and hundreds of images where they have. Colleges back in the 1870's would often consist of older men who would take years to graduate from prep-schools before finally being admitted, or would start later. Colleges would also employ non-students on their athletic teams in the days before formal requirements so dont let the ages of todays college students make you think that is the way it always was.
