Simply overlooked simply

Have you ever looked at a photo, read a caption if it had one, then moved on to something else. of course you have, everyone has. 
This photo below for instance, you probably assume at a cursory glance it's just another picture found on the web and posted here.Well you would be right...sort of.

But also not, you see when I found this picture on the web it didn't have speech balloons or words I had to add those.

It was also a color photo not a black and white photo, well, almost, you see, the idea behind doing this type of stuff s for humor. Part of the fun is either doing it perfect so you can't tell it's a fake, making sure it is off scale or tint so the person knows its a fake, or making it close to correct but a person would have to look to see that it isn't a true photo. The above photo is not a true photo, notice the stone is a little "off" and there is a shadow line behind the stone that doesn't match. The photo color was removed using "Irfanview" because the background was a color photo, the man with the guns was from a black and white photo... he was sitting in front of a barn.

I had to reduce him a little for scale.

That outhouse...

Current day photo,
I could have put someone else in the photo but it would have been a dead giveaway.
