The History of Ronald Reagan's T-Shirt

I love your t-shirt. I actually want one of them. Can you explain the history of this t-shirt, the significance of it? Where you got it and how much and where can I put it? I got it from San Francisco. There's a museum there that was kind of dedicated to the gay rights movement and having milk. This actual t-shirt is to do with ads, so the triangle is like this is similar for the ads, the morals and stuff. And it's obviously Spanish. Célinecio equals mourte. Silence is death.
