Scanlens

Scanlens is a brand of trading cards first produced in the 1930s and given away with packets of sweets and chewing gum.
The first sports-themed cards series were produced in limited quantities in 1963 featuring 18 players from the Victorian Football League and players in the New [South Wales Rugby Football League] and Queensland [Rugby League] competitions, which have since become highly sought-after, with some cards commanding a price of up to $2000 each. The record for a Scanlens card is $7,200, sold in 2014 and featuring Graham "Polly" Farmer; its high price was due to a misprint that greatly reduced supply.
Scanlens went on to produce further modern card sets between 1963 and 1991, many of which have since become collector's items.
