Brother Gorilla

I came across this on twitter today (posted by @SirWilliamD) and thought it the most moving (and uncomfortable) photograph I had seen in a long time. The caption was:

A poignant image of Guy the Gorilla in captivity at London Zoo c.1958 by Wolf Suschitzky. Taken by poking the camera through the bars. Wolf said he thought that this was his best photo.
