These lamp post banners don’t look that different, until you realize that they are attached only at the top, whereas in this country you attach them at both the top and bottom. I took this photo during a recent trip to Barcelona.
I took a closer look and realize that there’s a metal strap on each side to hold the lamp post banner into shape. Otherwise it would droop and be unreadable. It’s really just a different way of doing it.
One good thing about this design of lamp post banner is that it puts very little wind load on the lamp post. When the wind starts to blow, they just swing up and shed the wind.
