This image was formerly posed as a mystery ship - the ship on the left side - and, whether it was at Port Said or Alexandria, these have now been resolved.

Circa 1964-1969, Alexandria, Egypt.

The photo was taken from a passing Danish ship, possibly a DFDS cargo ship.

Three ships in this view, left to right:
1) Now expertly identified by Manfred, as the London Greek company Michalinos & Co. Ltd.'s 'Riverdore' - IMO 5297220
(A 5 cargo hatch, *unidentified* cargo ship, with black hull, red boot topping and a white line running forward to aft.
She has distinctive funnel colours: Black, with a broad light blue band and possibly letters in white thereon.)

2) Cunard's 'Caronia'- IMO 5064908
&
3) The United Arab Maritime Co's 'Algazayer' - IMO 5010804 or 'Syria' - IMO 5347520.
