A retro logo posted by the Atlanta Falcons set off a wave of jokes and Nazi comparisons online, according to The Guardian and NBC News.

The image shows the team's old falcon symbol on a background of red, white and black stripes, The Guardian reported. The bird dates to the 1960s and 1970s. The design is tied to Atlanta's home game against the San Francisco 49ers on Sunday, when the team is set to wear throwback uniforms, NBC News reported.

The Falcons put the image up on Instagram and X, NBC News reported. On X, it was labeled "New PFP," short for new profile picture. NBC News said the stripes looked like a war flag used by Germany in the World War II era.

The post on X had drawn more than 26 million views, The Guardian reported. Many replies mocked the design. "I give this a nein/10," one user wrote, according to The Guardian. Others called the team the "Bird Reich." Some jokes pointed to Atlanta's famous collapse in the 2017 Super Bowl, when the team blew a 28-3 lead to New England.

A team representative said the Falcons do not have a "new logo" and declined to comment further, NBC News reported.

Sports logo historian Chris Creamer said the team meant no harm, according to NBC News. He said teams often change their profile pictures to match throwback uniforms. "It's throwback weekend for the team," he said, adding that this is "a very common thing that social media accounts do across all sports."

The artwork appeared to be meant to honor the first Falcons team from 1966, NBC News reported.
