One comic i used to get was 2000AD with Judge dread.
The first edition had a plastic spinner, and the comic cost 5p.
This was a common freebie back in the 70`s not only given away in a lot of IPC magazines (Action, Starlord), but with a lot of junior comics from other publishers (The Beano, The Dandy). So too was its` "cousin", the 3 armed boomerang. This one looked a bit like that coat of arms on the back of Isle Of Man coinage.
