If you haven't heard of Bluey, you can bet the grandkids have.
The much-loved blue heeler is the star of the hughly popular Aussie animated TV series which has taken the world by storm.
And now, Australia Post is celebrating this national canine icon in its latest licensed stamp pack, launched on June 30.
Australia Post Philatelic Manager, Michael Zsolt, said the stamp pack was one for Bluey fans, the general public and collectors alike.
"The Bluey stamp pack will make a memorable keepsake with Bluey and her family featured on fun stamp shapes from our new MyStamps range. Look out also for the colourful picture of the family visiting a post shop inside," Mr Zsolt said.
Created in Brisbane by Joe Brumm and produced by Ludo Studio, Bluey follows the adventures of a lovable and inexhaustible six-year-old blue heeler dog who lives with her dad, mum and four-year-old sister Bingo.
"We never could have imagined that Bluey and her family would be dropping through letterboxes and into Australian homes so we were delighted to be asked to collaborate with Australia Post on this set of stamps," said Blue producer Sam Moor.
"We had a lot of fun creating the designs that feature in the Bluey stamp pack and we hope they put a smile on people's faces."
Since its launch in October 2018 the multi award-winning Australian animated series for preschool children has become the number one series on ABC iview.
The Bluey licensed stamp pack costs $15.50 each contains one sheetlet of 12 self-adhesive stamps featuring different Bluey character graphics and uses the new MyStamps range of personalised stamps.
The stamp pack is available across Australia at participating Post Offices, via mail order on 1800 331 794, and online at auspost.com.au/stamps while stocks last.
