One of the largest I've seen. I like the handwritten approach.

Creator: http://www.stoplawnlitter.org/. Apparently there's an entire website dedicated to these signs. Doesn't it make sense to consolidate environmental solutions into one website? Yes, it does; hence www.One-Earth.com.
Again, nicely done with the handmade lettering. Even the font is unique. The color red is effective because many of the people posting the unwanted material may not be able to read English and the use of the color red helps to reinforce the command 'stop'; it sort of transcends language. The maker of this sign thought it through completely. Very well done.
Our very own sign :) www.One-Earth.com (sign available for download).
This is hardcore. Notice the small 6pt font "Thank You" in the lower right. These guys are not messing around.
I like the hierarchy here. Also the symmetry works well (not sure that the second forward slash is necessary since "solicitations" is on the second line. Interesting that "Please" and "Thanks" are underlined.
At the bottom it reads, "Posted in accordance with NYS Law Chapter 585 of 2007. Violations will be reported." This is in fact a real law. Click here to read the entire law: http://www.stoplawnlitter.org/lawn-litter-law-sm.htm
I don't think there's a more direct way to say it.
NO. NO. NO.
The addition of Spanish makes this sign more effective.
