Settled in 1846 at the headwaters of the San Marcos river, by 1881 when the International-Great Northern Railroad (lower right) arrived, San Marcos was on its way to becoming a center for commerce and education. Every street is labeled on this bird's eye view and an index across the bottom indentifies 10 schools, churches and public buildings. This beautiful reproduction is printed on heavy, acid-free stock and is excellent for framing.
