All four of the images accessible here (click on the smaller images to change the central image) are of Haymarket police anniversary commemorations in the early 1960s. Their focus was the police monument, which, as noted, was then on the north side of Randolph Street just east of the Kennedy Expressway, a block west of Desplaines Street.

In the first image, dated 1964, an officer in period dress and a priest help lead the police officers' band west along Randolph Street toward the monument. In the second, a quartet of riflemen from American Legion Post 207, a Chicago Police unit of the Legion, takes aim in front of the statue as other members stand arrayed around the pedestal.

In the third photograph, dated May 17, 1963, the color guard in the background consists of members of the Junior Posse of Cook County. The group in front on either side of the officer in period dress includes Monsignor Vincent Cook of Chicago Catholic Charities, which was then located in its current building a block away on the southwest corner of Desplaines and Randolph; attorney John Tyrrell, son of last surviving Haymarket veteran Frank Tyrrell; John L. Sullivan, President of the Lieutenants' Association of Chicago Police; Patrick Quinn, President of the Police Sergeants Association; Paul Buhl, Chairman of the Haymarket Square Businessmen's Association; and Frank Carey, President of the Chicago Patrolman's Association.

In the last photograph, from May 18, 1962, the Chicago Police Post 207 American Legion Drum and Bugle Corps lines up for a wreath-laying ceremony at the monument.
