A picture is worth two nonwords

On July 14, 2011, we were at Bellis Fair in Bellingham, Washington. As we walked past Picture Perfect - which was closed at the time - this sign caught my eye. More specifically, the misspelling of appointments caught my eye. So I took a photo of it. As I got ready to post the photo here, I noticed the misspelled backgrounds. Interestingly, With The Exception Of necessary And backgounds backgrounds, Every Single Word Is Somehow Important Enough To Capitalize. I wonder why necessary and backgrounds don't deserve the special treatment. Click the image to enlarge it.
