1864, entire folded registered letter with acknowledgement of receipt addressed to Eversbach, franked on front with single stamps Coat of arms 10 soldi blue and 15 soldi brown and on reverse with vertical pair 5 soldi rose, all tied by superb strikes of cds. "FOKSCHAN 4 11" in blue with blue straigtline "RECOM..." alongside. The vertical pair with crease, some minor staining, otherwise a very attractive entire. Letters from Fokshan are extremely rare, according to Prof. Ferchenbauer just 2 further covers with stamps are recorded. This letter with a three-colour franking and unique usage as registered letter with acknowledgement of receipt represents one of the great rarities of the Austrian Levant as well as of Romania.Certificate Prof. Ferchenbauer VÖB (2019)
