Our guide led us down a narrow street in Cartegena where we encountered a man sitting on the pavement painting local scenes on little rectangle mirrors. He promised to demonstrate his technique by finishing a mirror in "two minutes, uh, maybe 20 seconds." He worked rapidly and a steady hand, working mostly with his fingers but adding a few fine brush strokes near the end. Everyone seemed mesmerized. I don't think anyone was timing him. When he finished he drew applause from the tour group. The guide translated the deal for him: one mirror for $7, or two for $10. The bargain hunters in our group knew a deal when they saw one. I don't think anyone bought just one mirror. Ours grace the wall in the foyer, a reminder of our trip to Colombia. I wondered if our guide gets a cut, or if the painter is his brother-in-law.
