Okay, I really feel terrible, so I'm going to go ahead and put up the first official clue tonight. I'm announcing it now so that everyone will have a fair stab at it.
I'm so torn up about this, I'm even going to re-set everyone's guesses for the day (even you, Larrikin).
This is only if you don't guess past this point, though. If you think you know it without the clue, by all means, guess away. You will forefit your freebie guesses for this evening, though. To put it another way, if you have already guessed today, you may guess again tonight after I put up the clue, but not until then - if you have not yet guessed today, you may guess now if you wish, but you will not be allowed to guess after I put up the clue tonight.
To again make this absolutely fair, I'll post the clue within five minutes following 10:30pm eastern tonight. That's about 9 hours and 5 minutes from the time of this post.
Again, I should have definitely included this along with the original graphic. Once you see the clue, you'll know the answer right away. At that point, it'll become a time game to see who can post the answer the fastest.
