Can you attach the amnesty international official logo file?

I have attached a variety of logos that can be used. I have also updated the brief. The update is just to let people know that we are looking for something cool to wear and the design does not have to scream human rights. We are after something different from our old designs and there is now also a link to that range.

should be nice if payment is guarantee?

We definitely have the money, but since we are a charity, we need to tick a couple of boxes before we choose a design.

So, all we have to do is to save the world in the next few days. Well, we'll be heroes! :)

Well if you save the world in the next few days, then I''ll be out of a job. I''ll be happy with a good t-shirt design that people will want to wear, then we''ll worry about saving the world.

Do you know if you have copies of you logo in vector format? Perhaps files ending in .ai .eps or .pdf? 

I have just added some EPS files for you.
