If anyone is interested in these then go to ' utahice.com/sanborn.htm ' ... For those that don't know, these are maps from around 1875---1920 of cities. These are very detailed, even showing property lines,poutbuildings, outhouses, wells, buildings, complete with building materials in some cases. This is one of the best maps I've found for nearly any place that was a city then. Lewis charges $1.00 per map. Yes one dollar!!!! If you buy a quantity he will cut you a deal better than that. I just purchased 118 maps from him. He sent me a disk with 120 maps on it. I paid $80.00. I received the disk in three days. It don't get no better except for free.
