Coca-Cola Russell Spinner Yo-Yo With Tricks Leaflet (1989)
Original string. These were huge for about five minutes in the late 80s.
I remember these well. Everyone had one, mainly thanks to the fact they had professional Yo-yo players going around the schools giving them away.
@MrRobotoUK I saw a clip recently of the little show-offs from back then. I could just about do the first two tricks and that's it.
