A macaque alone in a cage in a German laboratory inside Covance; photograph taken by or for the British Union for the Abolition of Vivisection, retrieved from with their knowledge. They have been contacted to ask whether they will release it under a free licence. It is likely that the image is in fact PD, as it was taken undercover, and most such images are released into the public domain. I am claiming fair use in the meantime because it has no commercial value, such a photograph cannot be obtained by other means, and it is being used for educational purposes to illustrate the treatment of macaque monkeys in European and North American laboratories.
