Excellent service and quick shipping with tracking and insurance. I've been VERY happy with my purchases.
I've purchased multiple sketch packs and animation cels and, although every sketch or cel isn't a main character in the pose you want, or from the most memorable scenes, they are top quality and a real piece of animation history.

I did have one problem. They sent out an incorrect Certificate of Authenticity. They sent a cert for GI Joe Resolute rather than GI Joe A Real American Hero, a simple mistake, someone grabbed the wrong one. A quick email to their support team and the correct cert was sent out within 48 hours with tracking.
The Animation Legends team is excellent.
