that’s a good sized mural..
and a busy road...
Easy to make a large cardboard stencil.
Four guys in a vehicle with yellow spray paint.
Chinese Fire Drill. Stop the car, cover the license plate as the stencil is being dragged onto the road way, four guys spray, grab the stencil, jump back in the car, speed away, and in some side road, remove the cover on the plate.
Wash, rinse, repeat. I like it.
