Poster shows "Stopera" in yellow on the handle of a dagger that is stabbing the center of a red rectangle with a black stripe running lengthwise down the center. X appears three times in white on the black stripe. Blood splatters above the dagger entry point and also pools below it. This represents the desire of left-wing and counter-culture groups (like squatter and Provo movements) to kill the construction of a building complex designed to house city hall and the national opera because it required razing many residential and historic buildings. Riots broke out when construction began. This is a call to gather in the area of the planned complex. Ink is red, yellow, and black.
