Should I put copyright info on pages?

[Whomsoever]

I'm about to start selling coloring pages as digital downloads. I already sell other things, so I am familiar with the listing process in general but I'm curious about weather or not sellers put copyright information on the bottom of the page. And while were at it, is there anything else I should know about listing coloring pages?
Thanks for the help!

I am curious about what other people do as well.

My sense was that it would detract from the image, so I decided not to include it.

I just put my signature in a bottom corner where it wouldn't be easy to get rid of but isn't destroying the image.

Ah good idea, Amelia.
