They're nice, Goom ^^
I'd rather buy a T-shirt with a sentence about Animorphs, but if we add a small logo with them, it'll be even better!
T-shirts with only a logo, or with a sentence like "Team Eric!" (so who are only for one Tvshow/series) aren't my favorite. I prefer sentences who don't really show what is it, not totally, unless you know the series, and who make people think about it ^^
