If there's one hand gesture that's become synonymous with hope and the tenacity of humanity in the "Hunger Games" movies, there's no doubt that the three-fingered salute would be it.

Countless times throughout the movies, we've seen the citizens of Panem use the salute to lend their silent support to Katniss. That's why it's only fitting that "Hunger Games" fans worldwide can unite today around brand new billboards featuring a mash-up of people of different genders, races and ages offering their own salute. The pictures include people from ages 8 to 80, from all over the world, offering their tribute to the worldwide phenomenon.

The billboards have been unveiled in 18 countries around the world, from Times Square in New York City to locales as far-flung as Colonne di San Lorenzo in Milan and Novy Arbat Avenue in Moscow.

Check out our exclusive first images of the powerful billboards below.
