This one I did before we left for Colombia. Another Green Lama - clothes are the same, but I made him older and did a better drawing.
These were done sometime between 2am and 3am when I spent the night at the airport in Bogota (thank you Aires airlines). Vacuum cleaner man did a good job of keeping people up, the other guy had the interesting technique of emptying his pockets and stuffing the contents into his shirt before taking a snooze. Finally, silhouette of guitar guy strumming in the corner.
My take on Fighting Yank.
