====Possible confusions====
* Mary Pottorff's name was often mis-spelled in a variety of ways, and in the tobacco archives she is often simply refered to as "Mopsy". Her initials were '''MOP.''' [http://legacy.library.ucsf.edu/tid/eex19e00] She signed herself "Mopsy" on internal memos from about mid-1985.* There was another person with the same surname, <u>"Jo Ann Pottorff</u>", who worked in the Kansas state office of the Tobacco Institute and stood as a Republican candidate for the State House of Representatives.

* Since Mary Pottorff worked with Philip Morris and had files handed down to her (and which included her own earlier letters from the CTR and Smokeless Tobacco Council day), some of the dates as they have been indexed (often estimated) may be incorrect -- they may date from an earlier or later period.
