Is there an international logo or symbol for animal rights?
While PETA is a very prominent organization, they have their own “logo.” Many times, people use the “NO” or “NOT” symbol (the red circle with the slash through it) along with a picture of what the “NO” or “NOT” is… but I do not know of any such usage for animal rights. If you look at the wikipedia article, there are links to other animal organizations at the bottom and you can contact any of them and ask them if they know of any such symbols. Of course, there are loads of t-shirts, bumper stickers, etc. already out there from these organizations if you wish to express yourself publically about your feelings. Have a right-wing day.
