There is an entry for the 1988 Adelaide Grand Prix souvenir token: N#297407
The event date is on the piece itself - 13th November 1988, and this is reflected in the text and the title on the page. However, the year issued is incorrectly listed as 1982.
I don't have any documentation around production of the piece…. but I'd go out on a limb and suggest it was NOT produced six years before the commemorated event :)
