This is an unusual set because different frames are used for each of the shows which makes it look like separate sets. Thunderbirds had red borders with a yellow border around the blast shaped inner frame - Captain Scarlet and the Mysterons had a blue border with a wavy frame in yellow - and Stingray had a greenish blue border with dots with another yellow wavy frame. The rather odd number in the set was because there are sixty-six cards for each. And apparently they were quite a short run - and were printed in Ireland. The cards measure 64 mm X 89mm
If you look about there are a number of unopened trade boxes about. These can be a bit reticent about the contents, so we can tell you that each box ought to contain thirty-six packets. Those packets, which were bought from it by the general public, sold for 20p each, and there were five cards per packet.
Our card shows the "Marineville" complex, which seems to have inspired several of the modern hotels. It was a town, in as much as people lived there, and you can read all about it at Wiki/Fandom/Marineville.
By the way if anyone can add any contemporary vintage cards showing Marineville we will add a note of them here.
