U.S. Topo maps date back to 1884. Those were very low resolution maps at a 1:250,000 scale at best (4 mile resolution) and most were 1:500,000 (8 mile resolution) or 1:1,000,000 (16 mile resolution).
It wasn't until 1947 that the maps that we know today as "topos" began to be made. Those modern 1:24000 topo maps have a best resolution of 40 foot. Those were made until 1992. Most areas had several topo updates through that 45 year period.
Around some of the major cities, including Little Rock, there are a few earlier 1:24000 topo maps that date as early as 1935.
