Late 60’s, early 70’s I want to say. As I remember, it was a black and white picture book about a black cat that gets out of it’s pet carrier(?) an walks through the city. I remember the pictures in this book being high quality black and white photographs. The most I can recall about the “plot” once the cat somehow gets out of it’s carrier it travels through the was once referred to as the “ghetto.” Anyways, it’s a long shot but the book had a huge influence on me about inner-city strife and that we as a people need to try to keep trying to improve everyone’s lot in life. I think this is a great little service you have. Cheers.
