Interesting. I am having a hard time finding more. The website doesn't look very interesting but I like that specific topic. If you have the link to more please provide.
My instinct tells me these photos are communicating a message from very specific sender(s) to very specific recipient(s).
I cannot define the message, the sender or the recipient but I know the instinct is to NOT QUESTION bomb scares. Wide open communication in public.
If you mean the Tim Osmon blog I didn't find it interesting. BUT I found the specific item you posted very interesting. Thanks for the reply.
