This an advertising campaign by an English school in Kyiv. I like the idea because there’s nothing better to do, when going up a rather long escalator, than to learn. The words, though, are poorly chosen. They are too abstract and I’m not sure they’d whet anyone’s appetite to arn the language.
l remember a few years back the London Underground started poetry on the underground. Famous poetry was shown at stations and on trains. Now, that worked well.
