The Poly-City football rivalry is the oldest American football rivalry in Maryland and one of the oldest public school rivalries in the U.S.—predated by the rivalry between the Boston Latin School and the English High School of Boston. The rivalry began in 1889, when a team from Baltimore City College (City) met a team from the Baltimore Polytechnic Institute (Poly), and has continued annually. Despite City's initial dominance in the series, Poly leads in overall wins with the record standing at 62–54–6.

This 26" x 9" "Poly" pennant is in great shape with bright colors and the tassels in tact. There are some pin holes and light fraying, but the pennant retains its overall integrity.
