This one seems more like a riddle, I was looking for famous places with gay happy faces...

I found that Montreal, Canada, is one of the most gay-friendly city, and that there is a famous place that has many murals... spectacular... I still can't exactly find the face, but the place is a spectacle: https://www.getyourguide.com/montreal-l195/montreal-street-art-mural-25-hour-guided-walking-tour-t270487/

I'll keep looking...
