In 1988 Turkey issued one stamp which shows us the “Fatih Sultan Meheth Bridge” https://en.wikipedia.org/wiki/Fatih_Sul ... met_Bridge
Under the bridge passing two vessels, the small watercraft on the top of the stamp looks like a small ferry crossing the Bosphorus, while the white hulled merchant ship looks like a reefer vessel.
Of both vessels, I have not any information.
