1891 University of Illinois player cabinet photos

These are some really rare 1891 University of Illinois football cabinets.  This was the second official season for the team.  They went 5-1 and defeated Indiana University twice.  Two of the cabinets are identified and 2 are unknown.  Frank Arms who is in some kind of lateral pass pose, was a member of the very first team.  All cabinets have the name Wright on the back.  There is a player Royal Wright who played in 1890 and 1891 so it may have been passed down from him.
