»Waller and Steiner: "The more you buy, the more you save!"

For the past month, I have not seen the Santa-hat-wearing fellow who sells books each Sunday mid-day at the corner of Waller and Steiner. He stopped me one morning out on the stoop, while he was negotiating three shopping carts laden with his stock-in-trade, and asked if I wanted to sell him the stuff I was putting out onto the sidewalk. I told him he could take it all in exchange for three books. I wonder if he's moved to another intersection? Have we fallen from favour? (He brought levity to the oddly grimy corner, and also kept it neatly swept. He gave picture-books to kids.)
