Street Sheet is a small monthly newspaper sold by homeless around the city. As 100% of your purchase of a Street Sheet goes to the vendor, it's a way to give money to the homeless as well as read about homeless issues in the city. The paper has a suggested minimum donation of $1.
The paper is printed by the Coalition on Homelessness, a non-profit organization, and they are funded by "sustainer" donations provided by individuals, as well as by underwriters. The paper has been around since 1989.
