Started and finished this in class today. It is part of an upcoming info graphic I'm doing for my portfolio and thought that using SF transportation would be great! I'm quite familiar with the F line street cars (various ones in colors and shapes and makes) from having to take this as part of my trips to an Industrial Design Drawing class I took during the summer. The line runs partly along Market Street and connects the Castro to Fisherman's Warf. The illustration itself took only about 5 hours and hopefully the others will be that short as well. Stay tuned for more!
