1944 DFJ, Vuk 2+3 stationery with message

I saw only two such postcards, both were unused and both with the same message on the back. I don't know if the message was prepared together with the original stationery or later with the DFJ provisional overprint.

1944 DFJ provisional issue, Vuk 2+3 din stationery with preprinted message on the back. Message was prepared for wounded soldiers in a military hospital in Smederevo.
