Previous winners have created inventive and inspiring artworks printed on 70,000 copies of the guide, which is distributed throughout Brighton & Hove and beyond.
Julian Caddy, CEO of Brighton Fringe, said:
"Brighton Fringe is all about giving people a platform to make things happen.
"It is a catalyst, a conduit for every possible kind of creative work to take place.
"It therefore makes for the greatest 'pool' of talent in the country, in one place, at the same time, and we invite the public to immerse themselves, to dive into what is on offer."
To be in with a chance to win, children under 12 years should create piece of original artwork inspired by this year"s tagline; 'Dive In'.
Designs can incorporate this theme in any way, but must not include local landmarks (i.e. Royal Pavilion, Brighton Palace Pier, i360).
The winner's artwork will be printed on the front of 70,000 copies of the Brighton Fringe Family Guide and they will win £200 to spend on tickets at Brighton Fringe 2020.
They will also receive a Gold Friends of Brighton Fringe membership entitling them to 2 for 1 offers on events and many more benefits.
Three runners-up will win two tickets to a Brighton Fringe children's show of their choice.
Entrants to the competition should use an A4 piece of paper in landscape orientation to design what they think 'dive in' means for Brighton Fringe.
The final cover image will be shrunk down to A5 – so the design should not include writing or drawing that is very small.
The closing date for entries is Friday 20 December 2019.
Please include the artist's name, age, school and a parent or guardian"s email on the back of the picture.
Send the landscape A4 artwork to:
