Historama Autumn Mail Auction #5

Pakistani postal boycott of Israel: 1968 a/m cv ex PRAGUE to REHOVOT, franked 1.60k & tied by unclear local pmk; this mis-routed via PAKISTAN, where marked in KARACHI by "KAR AIR/3 | MISSENT TO | PAKISTAN." IM h/s + m/s "No Service for Israel from Pak R-T-S [return to sender] P-T-O" & returned. This is one of only two known covers to Israel misrouted to Pakistan (both via Karachi): very rare as locale has had no postal relation w/Isr. since 1948 & no IM h/s has needed to be made. Rare instance of mail misrouted via Arab countries not in immediate proximity to Israel.
