I believe the more correct term for souvenir badges and pins with place names is 'travel pin'. These are prewar to current souvenirs of place visits.
There were badges issued during the war as souvenirs of places, battles and campaigns.
A very interesting sub genre with some beautiful enamel work. I started collecting these as a side project to my Norwegians fighting for and against the Axis powers, with a fair sized group fighting in Finland against the Russians. Many such pins and badges were purchased by the foreign fighters in Finland.
