Read Yourself Raw pin by Art Spiegelman/Françoise Mouly around 1980.
I had this pin as a teenager, and used to wear it on my jacket from time to time, to the great puzzlement of, well, everybody. But I lost it!
I found it on ebay they other day, so I just had to get one now. I was the only bidder. Mua ha ha. Preciouses.
The back is very standard.
