VTG "First Class Only" CRUISE SHIP SILVER NAPKIN RINGS set of 4

Description

VINTAGE SILVER "First Class Only" CRUISE SHIP NAPKIN RINGS Set of 4
Available for purchase is this rare vintage set of four silver napkin rings. The front has a picture of a cruise ship and says FIRST CLASS ONLY.
No additional markings, but there is a tag INDIA  on the inside some of the rings.
I think they were made for 1st class travelers only. (It may be from the Holland-Amerika Lines ship SS Nieuw Amsterdam which I saw brass First Class Only napkin rings online.) Each is in very good condition. I did not polish them, so there is some tarnish. I am selling 2 sets of 4. You can buy the round, oval or both. They look so similar that they would work for an 8 place setting. Let me know which style you would like.
I am unsure how old they are, but they are unique, vintage and very interesting items to own. I will combine shipping if you purchase both. See pics for best description.
