I almost hate to bring this up, but I don't think that a graphic made up of a capital A and three registered trademarks of other companies, including a checkmark, a red square and a boing ball, is legal grounds for copyright. The AO logo, at best, might qualify as a trade symbol, but combining logos clearly belonging to other companies, arranging them into one and calling them "mine" would, in all likelihood, never hold up under real legal scrutiny. It would be like me taking the CBS, NBC and ABC logos, putting them into a single graphic and saying "this is mine." It just isn't going to fly legally.
The AO logo itself is taking just as many shortcuts through copyright law as anyone who uses logos belonging to other trademark holders would be.
