I have a question on yaplakal:
Good night!
I propose to shake my brains, and think about this task, which I have already put before readers of many forums. No knowledge in special sciences will be required.
So there is a simple way to prove that the photo was taken not before a certain date. To do this, the frame includes the newspaper released on the day of the photo.
And now the question. Propose the same simple solution, allowing you to confirm that the photo was taken no later than a certain date.
All complex examinations of the period of existence, say, photo papers - exclude. Everything should be on the picture and accessible with relatively limited ability of the viewer.

One of the proposed methods killed:
>>> To take a photo with a guy. Kill a man. Carry a certificate of death with the date indicated. The photo was taken while the man was alive – not later than the date of his death.
