Herald Sun cartoonist Mark Knight's premiership posters have been revealed, but only after he got his head around drawing a new head: the GWS Giants' human mascot.

But Richmond's second grand final appearance in three years gave Knight a much easier task for the Tigers' poster.

The Giants' first appearance in the premiership decider comes eight years after their introduction to the league.

Much like the team turned the list around over and over, the mascot took some refining.

"The first drawing I did of the 'giant', with his red hair, it looked a little bit like Donald Trump so I had to start again," Knight told 7NEWS.

Fittingly for a giant, the premiership cup looks tiny in its large hand.

Two years after appearing with the premiership cup in its right hand and its left hand out like a Dustin Martin don't argue, Richmond's tiger this time is pumping its fist.

And the cup is a tattoo on its right shoulder.

"This one's sort of more joyous, it's got the double fist pump, which I guess is symbolic of two wins out of three years," Knight said.

All proceeds from the posters go to the Royal Children's Hospital.

Meanwhile, the teams have been named and it's official: Marlion Pickett will make his AFL debut in the grand final.

Richmond coach Damien Hardwick pulled the sensational selection move on Thursday after Jack Graham was ruled out with a dislocated shoulder.

Pickett, 27, was brought into the line-up to replace Graham in the team's only change from the preliminary final.

The Giants brought back Toby Greene (suspension) and Lachie Whitfield (appendix) at the expense of Bobby Hill and Lachie Keeffe, who were dropped.
