This is a strange one.
I saw these listed online as Trigan Empire Walkie Talkies.
They were manufactured by Otto Simon of the Netherlands, a company which is still trading. The box has a bar code.
The listing includes this Don Lawrence comic art as evidence that the box art is from the Trigan Empire.
Now I know precious little about the Trigan Empire but the walkie talkie box art doesn't seem related to it to me, although I could be way off the mark.
What do you think readers? Anyone speak Trigan?
