They were father and son but in their professional lives as successful cartoonists Paul and Bay Rigby spent many years working for rival newspapers in New York's cutthroat industry.
Over 60 years, Paul Rigby - a comic cartoonist for Perth's Daily News - made millions laugh with his witty, distinctive drawings.
The award-winning artist, who died in 2006, left a huge archive of work, some to be displayed at Gallows Gallery in Mosman Park from next week alongside the work of his late son Bay.
Bay Rigby, who died two years ago of a suspected drug overdose, was editorial cartoonist for the New York Post at the same time his father was a cartoonist for the New York Daily News.
"Bay was only 21 at the time and was an immediate success," his mother Marlene Rigby, who has helped co-ordinate the exhibition, said.
"Paul had left the Murdoch papers and moved to the opposition, but nothing fazes Rupert Murdoch - he simply rang Bay.
"There they were, the two of them, appearing in print with the same size cartoon on the same page of opposite papers every day. But their styles were very different."
Mrs Rigby said one of her favourite works was her husband's painting The Manipulators, which features media executives, including Kerry Packer and Rupert Murdoch.
Paul Rigby created more than 15,000 drawings during a prolific career that included five Walkley Awards for Cartoonist of the Year.
_The West Australian _'s cartoonist Dean Alston will open the exhibition on Monday night.
"Paul Rigby was a mould-breaker and his Daily News cartoons perfectly reflected changing times in the 1950s and 1960s," Alston said.
"His drawings were beautifully executed and his fine penmanship made every one collectable.
"His son was similarly gifted - both father and son have left a memorable legacy."
