This cartoon is a funny (cheeky) birthday card (could be for a 40th, 50th, 60th or whatever?) for a man (your dad, brother, uncle?) reaching a birthday milestone. It adds a little humour to the ageing process which can be anything but funny!
Tim Mellish was born in Brisbane, Australia in 1965. He has a degree in mathematics (statistics), is a keen runner and dabbles in a bit of martial arts… clearly the perfect background for a cartoonist.
