So it has been appearing that this is a poster for the upcoming Digimon Adventure 20th movie
It now appears that it will air in Spring 2020 and not in 2019 if this poster turns out to be real.
The logo for the new movie uses the same sort of style for the original 01 series which honestly looks great!
The poster hasn’t been released on the official http://digimon-adventure.net/ just yet so hopefully we will get some solided information if it is real.
So it turns out that this poster is official as it has now been tweeted by the official Digimon twitter account.
Credit for the poster goes to moetron.net
The official twitter account has now tweeted this poster for the upcoming movie!
