What’s in a slogan?

Why did I add the slogan to the cover, “The calendar with the edge”?  

Actually it started out, “The calendar with an edge”?   Was it too “gimmicky”?  

I kept hearing positive things about the benefit of the black edge around the weekly pages.  That simple feature really helps those who share the same challenge that I have.  I do not clearly see the edge of the page, especially  when it rests on a white work surface or on top of other papers.  So I decided to trademark this slogan and put it on the cover.  I’m proud to let people know that this calendar might help those who could use an “edge”.
