Great advertising on what appears to be the stairs of a subway station here in NYC.
Which only makes sense. The stations here are basically antiquated, and accessibility for wheelchair users and others with disabilities is almost non-existent. The ADA had been fighting with the city for a while over this, so hopefully this creative piece of marketing brings some awareness to the matter.
I don’t believe it is on the stairs themselves, but on a poster. The text just looks to be Photoshopped to me. I could be wrong though.
