One of the greatest rarities of all DFJ provisional issues is the overprint error "Југосливиjа" instead of “Југославиjа” that can be found on the nine values of Big Senta. For the "Famous women" and Porto stamps only two of each exist.
1944 Senta local provisional issue, all nine values of Big Senta with "Југосливиjа" error. Great rarity, only this set is known to me.
