"the letter has to show accidental"

Um, looks kind of staged to me....

I made this shot in "Campo de Fiori" market (Rome) on February 13th, 2010. At that time the Hidden Letter contest had not been launched yet.
I can send you the original shot so you can check the date it was shot.
Often reality exceeds immagination.

Oh I'm sure you did but what I'm saying is it "looks" staged and IMO, I think the better entries for this contest are those that are obvious that they could not have been staged.

Do you see where I'm coming from?

"To stage" means "to organize and/or prepare something", right?
I'm not sure I understand what you mean (it's not polemics, it's just "understanding English" ).
There was a piece of pumpkin waiting to be sold in a market, I liked its vivid colours and made the shot. When I made a search among my shots, I realized it looks like a "U" or a "J". So?...

Correct and this looks like it, IMO=In my opinion. Don't take it personal. Others may share a different opinion.

I see this as a walk by, and shoot! I also see an H, a J, and a U.

S, U and H

It's too bad that tarp was in the way.

Great find..

"S" ?

Yes.

It seemed a G to me.
