I'll always applaud any little contribution to the dissemination of Bitcoin to a new audience, but this caught my attention to think about how many people would read this? it is in a good spot for passersby, though the environment is not like a place where people stand to discuss or if benches were there it would have attracted more readers. The poster is okay and fine if it were to be stamped beside a bus stop. Whichever way, I'd say this form of awareness may not require people to read them there, it just needs them to see it and look it up on Google, then read in the comfort of their home.
Nowadays, we see all sorts of advertising regarding Bitcoin all over the place, in different countries and places, even in areas where Bitcoin is restricted. I really like the way the adoption is going and that more awareness is being created.
Only the person who took the original photo will be able to identify how that picture best fits in that area. There could also possibly be benches around the corner where people sit and have fun, which the camera did not cover up, or that place could also be a bus stop. Either way, the place is an open place, which means a lot of people pass through it every day, and the person who posted it sees the place as the best place for that. Even if one doesn't have enough time to stand and read through all the content in it, they could possibly take photos of it and read it through on their way home or even during their free time. There will also be people who will make fun of the image; others will also find it informative, which will definitely create a lot of awareness and let a lot of people know about it.
But funny enough, there are also a few Bitcoiners like me who have not actually read through the whole Bitcoin white paper; all I have been doing is going through a few posts where they post a few lines of the white paper information. I have downloaded the PDF but have not gathered enough time to read through it. If I come across such a situation in my street, it will really be a good opportunity for me to start somewhere.
