A 20-year-old Angeleno named Michael Sadri uploaded to Twitter last weekend the image of a poster showing Mexico’s iconic brown eagle devouring a Nazi flag instead of a serpent. It was a hit.

The tweet went viral. So he uploaded a collection of other anti-Nazi propaganda posters that were commissioned by the Mexican government in the 1940s during World War II.

Michael said he uploaded the poster to start a discussion about a little known moment in history and also because of echo current world events, namely Trump’s rise to power and animosity towards Mexico. “I’m not saying Trump is a Nazi, but he is an enemy,” Sadri said.

The posters seem to be resonating with people on social media. The eagle poster alone garnered more than 2,000 retweets and sparked dozens of comments.

The University of Princeton has a digital library with some of the best works of this Mexican collective:
