Request for information on interwar folk celebrations in western and central Slovakia

We recently received this request from Dr. Patrice M. Dabrowski:

I am looking for information on popular folk celebrations held in places such as Trencin and Turciansky Svaty Martin in the interwar period (circa 1930 or before), celebrations at which I gather various state dignitaries, including Masaryk, appeared. Can anyone suggest where I might look for such information? In addition, I would love to learn if anyone is working on, or has worked on, tourism in the Tatra Mountains. I myself am writing about what I call the "discovery" of the Carpathians from the northern and eastern sides (that is, by Poles and Ukrainians).

With thanks in advance for your help,
