GENERAL STEAM NAVIGATION CO. LTD. OF GREECE.

The early livery was that of Goulandris Brothers. A blue flag with white Greek gamma is confirmed by postcard evidence. Rosanoski notes that Talbot-Booth’s wartime books instead show white with blue gamma. Greek-registered ships used gamma, while British- or Liberian-registered vessels used a white Latin G. The line adopted its own livery in 1954.

Brown 1951 shows a minute difference from its adjacent Goulandris livery and places the company in New York.

Bonsor describes the 1954 flag as blue with a yellow trident and a yellow-and-light-blue ropework base. Rosanoski initially assumed gamma forms on either side to match the funnel, since the verbal description does not mention them. An unframed postcard version instead appears as a stylised yellow crown with an arrow-like central stem and a yellow-and-white wreath or rope base. Ocean Ships places the funnel device on the blue band, while a pamphlet extends it onto the black top.

Olympia’s postcard confirms the funnel. Harnack’s notes of 2 January 1957 appear to draw on a flag measuring twelve by eight feet and show a yellow frame around a gamma and reversed gamma with a yellow-and-blue wreath. A Dutch chart depicts a yellow inner border and an arrow-like central element between mirrored gammas, above a short yellow rope, together forming a crown. Harnack does not describe the central element; Rosanoski thinks it resembles a spear or harpoon more than Bonsor’s trident.
