This Jack vinyl figure is released by Funko in their POP! Movies x Titanic vinyl figure series.

Funko POP! is a crossover vinyl figure series by Funko and other famous franchises such as Disney, Pixar, DC Comics, Marvel Comics, Simpsons, South Park, Uglydoll, etc. Each POP! figure is about ~3" to ~5" tall and crafted in a Japanese anime/manga super-deformed style (NOTE: due to the unique design of each character, the actual size of the figures may be smaller or bigger than stated).

The POP! Movies x Titanic features characters from the American epic romance and disaster film that tells fictionalized story of the sinking of the RMS Titanic. The film follows Jack Dawson and Rose DeWitt Bukater, who are of different social classes. They fall in love after meeting aboard the ship, but it was not good for a rich girl to fall in love with a poor boy in 1912.
