Kent State Shooting Protest Posters

I fount most of these on a Tumblr page, from the post

Quote:

Posters relating to the murder of four Kent State students by national guardsman at an anti-war protest on May 4, 1970. Another 30 students were wounded, one of whom was paralyzed for life after the troops opened fire on the large crowd of youths on the campus.
The killings followed days of protest around the campus and the country after the Nixon administration launched the invasion of Cambodia.
More protests and heavy riots swept through numerous American cities in the week following the murder of the students.
On May 15, 1970 police killed another two students and wounded 12 more at Jackson State University during a riotous protest.
