Porto = postage due
so probably at the end of Yugoslavia in your catalogue.

Hi guyana1230 (and welcome back) in SG Stamps of the World, these stamps are only listed with elaborate overprints. A search on eBay finds two examples similar to yours but with certificates. The overprints must be easily forged. All the best, Daniel |

Have been informed that these are locally produced postage dues that would only be listed in a specialised pre-Yugoslavia catalogue. Thanks to those that tried to help.
