This seems like a problem for the article in that I just searched the New York Times and the Washington Post and I couldn't find any articles about this.  Last spring I found several websites that showed altered tea party photos, the before and after, so I went looking, but I couldn't find before and after photos of the Dale Robertson sign.   

 Points to think about: 
 *who took this picture?   
 *Why doesn't Dale Robertson show the original sign to reporters so they can see that it was photoshopped?   
 *Why aren't there reliable sources? 
 *If this is a credible story, why not report on it?  

 Points to think in asking whether or not to delete this section:  
 *Is this widely reported?   
 *Does it have reliable sources?   
 *Can it be written, using reliable sources, in neutral language?
