It's actually four separate panos end to end in one large Japanese Album Moleskine, all of which I drew on site in downtown San Antonio. The first is a 180 degree sketch of Houston Street just north of Alamo Plaza. The second 180 degree pano is of Navarro Street and the Nix Hospital. The third is on Commerce Street and features the Aztec Theater. The fourth pano is only 90 degrees (I ran out of room) and was done in front of the old San Antonio Courthouse. They are all stitched together by means of a transitional device I borrowed from Urban Sketcher Pete Scully-- a light pole or street sign is used as a divider between panoramas, and fortunately I was able to use what was already there.
