This gentleman lives across the street from where we usually stay in Havana. He sells old currency, post cards, and a few old magazines. He is sort of the neighborhood watch guy I suppose. He is always in his doorway, behind a little table upon which he spreads his merchandise, and is quite friendly. Many people have little streetside businesses like this. Some refill lighters with insecticides using the flammable properties of the propellant. Others sell coffee or juice, some sell cookies, some repair clothes or shoes. Really just about anything to eke out a little more money to put toward survival.
