Another Montage!

I was searching for inspiration on the internet for my montage-related post to save my grade, and I found a montage that I actually like pretty well. It's by Peter Roehr, who died in 1968, hence it is all in black in white. There's a selection of 4 segments of the montage, and I really liked the last two. A quote from Roehr says that he changes material "by repeating it unchanged. The message is the behaviour of the material in response to the frequency of its repitition." The montage was presented at the Prospect 71 festival in Dusseldorf. I just thought it was an interesting take on presenting images.
