Remember this? It was a sticker and we said it wouldn't last the Nelson summer. Ben told me quite a while ago that they did something to remedy it, so last week I went to investigate. Now two new leaves (I couldn't tell if it was an identical sticker to the previous one) are affixed to a thin piece of plaster-like white board, which is screwed to the cement block wall. From a distance it almost looks like the old sticker, but the green leaves are less vivid, because of the white instead of the gray background, and you see the screws all over the place.
I vote for painting the leaves: it's probably cheaper in the long run.
