The 1875 Winneshiek County map below is from the David Rumsey Historical Map Collection and as one can see, even though it shows the sections of each township, it is not a plat map. Rumsey scanned this image from A. T. Andreas' illustrated historical atlas of the State of Iowa.

What is interesting is if one examines the detail of Glenwood township below, one can see B. B. Sander's name at the bottom of Section 22.
