I would like to know if ATC is for members use only on E-bay. I looked for a group on search but did not find anything. I also guess I want to know about ACEO....I don't want to do the wrong thing, but my creativity is wanting to go crazy and create, create, create! I just joined this group and viewing all the wonderful artist's work makes me want to do my own things!!
Thanks,
Hartnio

The answer to your question is a bit tricky. We'll start with this:
A standard ATC (artist trading card) is 2 1/2" x 3 1/2". The same size as a standard baseball (or any other) trading card.
In their inception, the idea behind ATC's was that they were to be traded between artists, by artists, and only traded - never sold.
However, ever industrial artists soon realized that these wonderful little works of art had a potential market value. ATCs first began selling on eBay several years ago - and in an attempt to separate those being sold from those that were only traded - they coined a new acronym - ACEO, which stands for: Art Cards Editions and Originals. ACEOs are the same in size standard as any other ATC, however, they are offered for sale. You can now find ACEOs for sale on etsy, eBay, personal art websites, and other sales venues. At any given time, ACEO listings on eBay can number in the thousands. Just recently, eBay assigned ACEOs their own category. You can find ACEOs for sale at prices that range from under a dollar, to final bid prices that end in the hundreds. The sales market for ACEOs is not going to go away.
While there are several art groups on eBay dedicated to ACEOs (ACEO and ACEO and ATC Enthusiasts of particular note) - it is not necessary to be a member of any group in order to use the term ACEO in your listing. The term ACEO at present is not trademarked (unlike ZNE) and the term represents a specific size of art, not the name of a group only (again, unlike ZNE which is a group name). So, if you are selling ACEOs, you can feel free to use that term in your listings. Many people also now use the term ATC in their listings - though it is slightly less common for sales and sometimes frowned upon by others who feel that ATCs should not be offered for sale. Whethor or not you use that term in your listings is up to you.
Whatever you do - always enjoy creating, and best of luck with your sales!
