Here we have Mystery Photo Number Thirteen. Your mission, should you choose to accept it, is to help figure out the who/when/where of the photo. Plus, in this case, the photographer, who tells me, "Make 'em work for it!"
No larger view this time.
Thanks to all who have sent in photos. Feel free to send in more, by emailing them to mystery At humbug .com. (Your own photos only, please.)
