It pained me to go through them all. I imagine the days when they were built and the hopes and dreams that surrounded them. It is a pity and shame to see the condition today. Makes me want to fix some of them up. Also makes me wonder 100 years from now what condition our houses will be in. Many houses today are built w/lesser quality, cheaper construction materials.
Edit: Cool that you can purchase prints and money goes to organization doing positive work in Detroit (preferably), or in other cities around the country. Organizations like Habitat for Humanity, and The Greening of Detroit.
