This is an image of the M.S. Stella Solaris (formerly S.S. Camboge) which was the pride of the Sun Lines cruise ship company in the latter part of the 20th Century.

The caption on the back states simply:
Sun Line M.S. Stella Solaris Greek Registry

–This ship was active in the Aegean cruise trade for many summers from the early 1970s until the end of the century. In winter it made tours of the Caribbean. It was finally scrapped in the early 2000s as newer, much larger and more economically efficient ships were developed.

This card came into my possession because my parents took an Aegean cruise on this vessel and sent the card back to my mother’s mother as a souvenir. As it was used, the card is dated June 11, 1977.

The original marble statues have been removed and replaced with castings, since the intense pollution and acidic rain of modern Athens was literally melting the marble away. This photo shows them before removal and the beginning of extensive renovation of the structure.
The postcard was used and has the date of June 4, 1977.
