Stamps & Covers Public Auction 357

Croatia: 1941 cover with provisional usage of Ustasha propaganda stamps 50b red & 1K blue (instead of normal postage stamps!), tied by 'Crikvenica / 18.VI.41' cds, used to Italy with 'Fiume 23.6.41' arrival cds on front. Plus also a stampless cover with 'Crikvenica / 25.V.41' cds & m/script 'posta ostala bez marke' (PO is left w/o stamps), thus proving that this coastal town PO had totally run out of stamps. Amazing & probably unique usage. 2015 Dr Colla AIEP & 2018 Ceremuga photo certs. (P)
