Personalized Subway Art

I made some subway art using the addresses of all the places we've lived since we've been married. I printed it at Kinkos on foam board at 16x24. I love the way it turned out except the color. I really need to calibrate my monitor, but I don't know how. Colors always come back dingy and dark. But it still works. I hung it in my kitchen. Super easy and personalized.
