I was a bit wary when you yourself proclaimed that your own art was amazing but you provided the goods to back it up, so bully for you
Welcome to eplaya.
I believe it was the French Quarter village that had something similar back in 2012 - it was in "Chinatown" with rad UV art lining the "back alley" walls. Maybe contact them? But really, you don't need much of a showcase - set it up alongside your own little camp and plenty of people will appreciate it!
When he lights his streetlamp, it is as if he brought one more star to life, or one flower.
When he puts out his lamp, he sends the flower, or the star, to sleep.
That is a beautiful occupation.
