Thurgau is split into two parts - aren't the Swiss playing cards used in the whole canton? edit

Hej guys, nice article! I just stumbled on the surprising depiction of the usage of the Swiss playing cards in the canton Thurgau. It's split for some reason and I'm not sure why. The boarders of the canton are according to this: https://en.wikipedia.org/wiki/Thurgau#/media/File:Karte_Kanton_Thurgau_Bezirke_2011.png I've not come across anyone using the French playing cards in this region. Is there some source which supports this split? Would be interesting to know. — Preceding unsigned comment added by Mijamaka (talkcontribs) 19:19, 10 April 2016 (UTC)Reply
