I read on another post that the back of the card will be generic, as least for the time being. Therefore, no copyright notice to indicate ownership of the artwork.
 
For maximum legal protection, I want to display a copyright symbol and my name. Would the only option be to discretely include it with the cover art? Or perhaps somehow inside the card?

Hi
Maybe the option of actually adding a discreet personal copyright to the actual image before using on the card, I do this on my photography and wondered about doing so on my cards too, more unique to the artist that way.  
I haven`t done so as yet but wondered what the general opinion would be?
