In 2012 during the WSC/WPC in Croatia, the future host of the championships - China - proposed that the WPF should design a WPF flag. This symbol would be used in a similar way as the Olympic flag, i.e. it should be handed over from one host to the next one and lifted up during every opening ceremony. 

This idea was accepted and the Design competition was announced. Anybody could send the designs to the WPF. There was a condition that the logo of the WPF needed to be presented there.
These are the designs received from various authors.

All the WPF members (Personal members included) are asked to vote for one design. The winning flag will be sent to the Chinese team and they will be the first country to use it during the championships.
