Thanks for your reply. Since I wrote this I have thought about the scans of my paintings and I have to agree with you as to calling them "a print of an original art work".
However,the reason for the first question as to using the same image for both ATCs and ACEOs is because I do a lot of digital painting (not photo manipulation) on the computer. There is no, as you put it,"real piece of original art" ,ie, hard copy that can be held in ones hand, until it is printed out. In the case of my digital paintings I would like to use same image for both ATCs and ACEOs.
Since I asked this question I've come to the conclusion in my mind that my "prints" of my digital paintings are in fact "real original works of art" because I created it and it becomes "real" to the world when I print it out. I've answered my own question to my satisfaction and I'm going to call the ATCs and ACEOs I make from my digital works "real original works of art", be it an ATC I trade or an ACEO I sell. Of course I'll let it be know that it was created digitally. If that isn't okay, sorry, so be it. To me digitally created art is every bit as viable as a physically created piece. It takes the same creative process and effort as every other medium to create an original piece, its just that the tools are different.
Thanks again Angie for your reply.

Perception is all important. A person does not merely see what is before him, what they see is influenced and based on their own personnal experiences
