Some clever human has modified a sign inside of a G Train car to display the above Anti-Nazi symbol. The sign was spotted by G Train rider Wesley Verhoeve. This common sign usually shows a boombox as you can see in the below pic, but has been modified to show something much more pertinent.
Nice alteration on the G train. pic.twitter.com/jVh6oQiigF
