7.1943 Sarajevo to Zaprešić rare Domobran letter

Mailed from Sarajevo by a member of 2.sat Sarajevska posadana bojna (2.company of  Sarajevo garisson battalion) to a member of 1.sat 4.željeznička stražarska (ŽESTRA) bojna, in Zaprešić near Zagreb (1.company 4.railway protection battalion). Zaprešić is misspelled on the cover as Zapršić. 

The sender drew a square in the top right corner with a big letter T inside and text "Spoložaja". T means postage due was to be paid ( from french 'Taxe')  while text 'Spoložaja' is Croatian meaning "from the (battlefield) position". This square was cancelled by the Sarajevo post office and letter was accepted for mailing with postage due to be paid. There is no arrival cancel or marks that postage due was collected. Croatian soldiers were supposed to pay regular postal charges.

Probably this was philatelicaly inspired letter, but it was recognised as curiosity already during the War. This letter was published in the philatelic magazine 'Hrvatska Filatelistika' in issue No.10-12 of 1944 on page 153.

What's  unique with this feldpost card is that it was mailed by a WOMAN ! This is the first card I have seen written by an Croatian woman serving with K.u.k army. She states her name Ljubica Hercezi  and she is "K.u.k Lehrerin in Kragujevac Krieskommando", while official purple cancel reads Ökonomieamt, hence she is a teacher working in a economic office of the K.u.K. command

Text is in Croatian, she sends greetings to a lady friend in Zagreb, and writes she had appendicitis, and maybe she will return home for a recovery.

6.1943- SS feldpost, postal card to Cernik Slavonia (7.SS Prinz Eugen)

 14.06.1943 feldpost card mailed  from a Croatian soldier to home in Cernik near  Nova Gradiška in Slavonia, Croatia. Card is written in Croatian, text is usual greetings, ordinary Croatian postal card was used, clear arrival cancel Cernik is from 12.07.1943. Soldier hasn't written his feldpost address and units cancel is illegible hence it is impossible to find out from which unit it was mailed. The only clue is a red censor cancel , SS-Gepruft used by the SS. The sole SS unit active in Croatia in June 1943 was 7.SS division Prinz Eugen and this card was almost certainly mailed from it, other SS units like 13. Handzar and SS police were still in formation then.
