As you see on the map [‘Ostsee-Provinzen’ from Meyers Konv.-Lexicon, 6th ed., about 1905] Dobele is a little place near Mitau, the German name for the Latvian Jelgava. In the postmark on the address-side here below you see the Russian name for Jelgava: МИТАВА (MITAWA), where the card is sent.

In the arrival postmark is indicated ЛИБАВА [LIBAVA], in Latvian Liepāja, in German also known as Libau (address!).
In the arrival postmark is also indicated the governement: Courland: abbreviation of КУРЛЯНДСКАЯ (KURLYANDSKAYA) ГУБЕРНIЯ (GUBERNIYA), Courland Government.

According Baedeker (1914) Dobele was in that time a very small town: “… Doblen, a small town with 2000 inhab., picturesquely situated on the Behrse. It is commanded by the well-preserved ruin of s Castle of the time of the Teutonic Knights, which stands on the top of a hill descending precipitously to the river.”
